Hi Gang, I have a question about how these pumps are supposed to be plumbed into the washer fluid line that goes to the nozzles. Here's how the PO did it. I suspect this is not the answer. In my truck I have two electrical connectors, one for each pump, and the low fluid connector (glad I installed the bulb :-D )and one rubber hose that passes up through the firewall into the wiper motor/mechanism compartment where it Tee's off to each nozzle. What it the correct way to plumb this system? I'm thinking a hose off each pump to a Tee then from the T to the firewall hose but wonder what the factory did and what others with this bottle have done. Thanks in advance

I know it's a weird tip but it works. Vaseline, yup good old petroleum jelly, it's great for holding marts together, things like needle bearings in a transmission, weird little plastic parts that move against each other (high beam switch slider in wiper switch). Super handy plus it's fun to say!

More headway and just in time for the endless gray season! I installed a rebuilt wiper motor and a new wiper delay switch and lever (to git rid of the last visual vestiges of Cruise Control ) also a wiper control module from Deadjeep.com I now have fully functioning wipers! I followed the wiper mechanism rebuild guide found on this site and all went well! I did go through 2 wiper control modules before getting one that worked but the gang and deadjeep.com sent out the 2nd of free of charge and no questions asked, super awesome! Last part of that system is on the way from Ebay a used, not broken wiper fluid bottle. I have one and the pumps are good but it has a smashed in top. Not sure how that happens but I guess it does in the bushes lolz. I still have some work to do on the cab lighting but overall I'd say I'm done working on electrical and will move onto the brakes next, then the engine itself. Thanks to everybody here, this site has been a goldmine of info and support, can't wait until I get the old Heep on the road!

I've gone the route of having a 302 balanced and blue printed, then did the assembly myself, however I was younger then and now I like the comfort of having some things done by folks who do it all the time. Since you're options seem limited I'd have Shop #1 do the rebuild so you can drop it off then pick it up when it's ready. No matter the route you take you will need to break it in properly as mentioned. Alternately you could get a junk yard engine (maybe? not sure what th junk yard status is like over there)

Nice build thread, thanks for the part numbers and links makes life easier! Can't wait to see pics and video of you HAMMERING DOWN on the trail

Ha ha Thanks guys. O.k. I made some more progress yesterday, pulled the old fuel pump and discovered why the fuel gauge didn't do anything: Evidently you need a sending unit and a float or something Thanks to mtscompany.com for having new, in stock sender/pumps shipped for $159. model # JPSU-6P4.0 shown in photo above. Then I spliced in a new fuel pump sender pigtail into the harness to unf*** the POs mess, and discovered I was out of gas as the low fuel ight came on (yea!) I added 3 gallons (what I had laying around) and the fuel level indicator rose and the light went out. Super stoked to have a working fuel gauge again. My Scrambler fuel gauge only ever "worked" when it was my daily driver I ran out of gas more that once, I got good at adding fuel on the 520 floating bridge, ha ha ha. At any rate my "last" electrical project of Summer (now fall) will be replacing the wiper motor so I can have all the speeds, not just slow. I've learned a lot about this truck and have squared away lots of gigs along the way. Thanks for all the help gang, I'm sure to need more during the next phases as they come along.

That's a good thing , double checked with SSL ping

So which cluster do I appear to have here? I think if I knew that it might help me figure out how to fix it, if I can't fix it then I'll be sending you some $$

Thanks guys, I'll try posting up tech questions in the tech zone. As for the reverse lights I found the disconnected wire, it was the black and yellow one hanging out of the harness near the ECU. Once I plugged it in the reverse lights came back on. Regarding the oil pressure gauge, when I had the cluster out I moved the indicator to zero and it moved back to it's current position, even out of the truck. So perhaps it's broken. EagleScout you got any of these laying around? (do you want more of my $ ? haw haw haw...) I have a blue cluster, with all the gauges. When it was out I cleaned up all the contacts, unscrewed each gauge screw, cleaned and replaced it and it's contacts, then replaced all the bulbs in an attempt to not have to take the cluster out again anytime soon. I'f I can't get new gauges or get these ones to work I may opt for some mechanical after market ones since I like to know what my oil pressure and engine temperatures are!

Well i now have all 4 hazards, brake and running lights as well as turn signals! The reverse lights were working but stopped for some reason, that's up next. What I've learned with this electrical system is, GROUND EVERYTHING, THEN GROUND THE GROUNDS WITH ANOTHER GROUND THAT IS GROUNDED My guess on the reverse lights is a ... (wait for it) GROUND ha ha ha ha!! I am losing my mind over here in smoke city. Glad I have Jeep to keep me grounded... O.k. enough jokes, seriously it's been a fun thing to work on in these crazy times and I'm making progress! A few odd things to iron out before I start on the drivetrain, brakes, cooling etc are: 1. Do gauges "go bad" or is it typically just a bad connection somewhere? a. My Oil pressure gauge just sticks around 15 psi, even if I disconnect the sending unit wire, where my temp gauge moves then goes to zero when it's unplugged (sending unit it broken off in block) b. Can I replace the gauges with after market ones or from other model Jeeps of the same vintage? if so anyone have tips there seems to be lots of discussion but Ihaven't found any answers that relate to my problems. 2. The lights in the B pillar, are they supposed to turn on with the under dash lights (turning the headlight switch all the way to the right, or left, can't remember the direction, remember I'm losing my mind) That's all for now I think I'll go dig into the reverse lights some more

On my Jeep it appears that the temp sending unit has been broken off Is there another way to bleed the cooling system that does not require removing that sensor? I just changed the heater core but did not drain the whole system, I think I can get by with just filling the heater core I understand I should replace all the coolant but it is still bright green and seems to be in good shape. I intend to replace the radiator "soon" with one that has a filler neck on it and likely drill the hole in the t-stat and will refresh the coolant at that time. I don't want to try to get the sensor base out with a bolt extractor at this time because it is keeping a seal and i need to move the Jeep. I suspect I'll need to remove the head to properly remove the sensor but don't have the time to do that right now. Any guidance is appreciated, thanks all EDIT: I was able to burp the Heater core due to the "Prestone" flush fitting in the top heater hose, I simply un screwed the cap, then pushed the hose down (so it's lower than the level of coolant in the reservoir) I did that a few times, added more coolant and viola, she's topped off! At least it's good enough for now.

O.k. some progress has been made, Still working out my turn signals and hazards, which let to the steering column and removing the guage cluster. Since I was in so deep and the weather is nice I decided to pull out the dash and get on the de-mouse-pee smell task. Here's what I found in oder (ha ha pun intended) The initial find from behind the blower motor: Then I pulled the whole heater box assemble out and found more evidence (this is where the mouse nest dust cloud came from when I turned on the blower..ugh) After pulling the top off of the case I saw the full monty notice on the right half of the last photo the "dirt" that's my actual smell, it was a brick of mouse poop and pee baked into the heater core and is why the smell started about 2-5 minutes after running the truck. So I rinsed all the crap out, pulled the AC exchanger out (I eliminated my AC as well since is was already discharged and BEAT UP), then I washed all of the heater box compnents with "Rocco and Roxie" Pet stain eliminator, it's and enzyme spray we use to clean up after our cats, it works great and after washing these part twice with it I didn't rise the soap from the foam %100 to help continue breaking down any residual odors. Now the heater box is back in, with a new heater core (I don't want to pull that box again) and this afternoon I hope to have my steering wheel put back together and possibly get the dash back in the truck. MY goal is to be able to drive the truck around the yard by Sunday, we've got more black berries to move!

Dana 80s have huge pumpkins, 60's can be ground down a bit and are more "compact" to start with, plus more gear ratio variety :-D Dana 300 T-case is the work horse of the CJ, and with a fairly easy mod can allow for twin stick gear selection, mostly useful for front dig

Dana 60s front and rear, Dana 300 T-case, T-18 transmission go big if your going to go big

Well after reading the wiring diagram (Thanks JMO413, that guide has been super useful!) I figured out my "dark Blue" wire was shorting somewhere, after pulling connectors I was able to to narrow it down to the rear part of the harness. The PO had run some extra lights and wiring down the harness so I pulled it all out (the harness too) and did some inspection. I found one of the two 2xDK B and 1x B connectors for the license plate ligts were connected! Since I had the harness out I solders up the ground and DK B bundles, plugged it all back together and now I have marker lights...and nop brake, turn signals hazards or the once working reverse lights. UGH... lectrical man it's a pain in tha ***! Oh well we had some yard work to do and I needed to drive the Jeep so I threw the steering wheel back on and loaded up some blackberry bundles we made last week (we have A LOT of blackberry bushes) to get them out of sight! As for the wiring I think I had a bad ground in the rear all along, I'm going to buy new hazard and turn signal flashers and hope I get my brake lights back. I am so deep into this I think I should cut to the chase and replace the turn signal/hazard switch/harness in the steering column just for peace of mind. I really want to get the lighting to work properly so I can start digging into other stuff like brakes, valve cover and cooling system < STUFF I KNOW HOW TO DO! Lol living on the learning curve is how you learn !

Hi Blue XJ, any chance of drawing and posting a down and dirty wiring diagram? Even something drawn on a napkin works, I just need a visual of how the wires interconnect in relation to the switched power and the relays. I have doors from a 99 and plan to install them on my 89, thanks for the help!

Anyone have a spare you’d be willing to sell? I’m tired of reaching into the abyss to pop the brake 😁

No thanks I don't intend to use it, ever. Thanks for the offer though it's appreciated! Watchamakalit PM me with your list of wants, as I said I don't plan to reuse any of the CC stuff.

Awwright I got my reverse lights working! Woot The sending unit was fine but the crimp-spliced harness wires were wet with oil so I cut em, soldered them and heat shrinked them, now I'm up and running. Still no running lights though oh well more things to check out, light switch, fusable links etc.

I made some progress today. Had to take a break from trying to get the turn signals working, decided to eliminate the cruise control. I started at the throttle control on the manifold and worked my way back to the vacuum, then the wiring. Ultimately I discovered the big white connector: Is supposed to attache to my non-existant cruise control module, so out came the wiring, pass through hose et al. Removing that system made it easier to see the base system of the brake wiring, and got rid of a few more what does this wire do/go to. Super awesome. I also cleaned up the vacuum axle actuator lines that are no longer in use since the PO did an axle swap, so no vacuum, actuated front axle for me. More discoveries: The wiring to the reverse switch on the transmission isn't connected to the correct sensor/sending unit (I think. More research needed) need to sort tyhis out to get my reverse lights working. The transfer case position sensor has no wire leading to it (as far as I can tell) not sure that I really care I know where 4 low is. Overall this has been a productive a.m. I'm going to eat lunch, read up on the reverse sending unit and see what more I can do!

I just ordered these from O'Reily's, $10 each new part number; 85898 This is a great site, plenty of useful topics, thanks!

Thanks for the tips guys, After taking a closer look at the fuse "box" I noticed some kooky fuse behind it coming out of the back, along with the burnt out and missing fuse connections I figured the Jeep came with a "new" fuse box for a reason. Sure enough, somebody rewired this, why? and seemingly wherever looked good? In the process And finished! After the swap my heater blower, AC pump (no coolant so it's not cold), bed light, hazards, wipers, tach, all work as expected. Glad I did this early, I'd have been chasing my tail otherwise. Next up keep on keepin on the electrical tasks, once those are ironed out I'll deal with the mechanical issues since those, to me, are easier. I may skip to remove the heater box because when I turned on the fan a dust cloud of mouse nest filled the cab.. guess I know where that smell is coming from :-D !

Thanks for the tips "J.E.E.P." and Eagle I should be able to get it out easier with these tips.

Thanks for the response, it's an 1989, I have large hands and wrists so I may just drop the steering column to gain access.

Add on question, what is the magic to detach the speedo cable from the gauge? I gather there is a clip to squeeze but from where or what angle?
