I have an 89' 4.0 eliminator, and my pump looks just like the bottom picture. It has the black plastic reservoir. The pump has a opening with an o-ring for the nipple off the reservoir. It also should have the pressure valve and spring where the high pressure line threads into. It also has two black clips that hold the reservoir to the pump.

Well we have cruise control, LOAD definately has a impact of the performance of the CC system. You can test many of the components for functionality, both on or off the truck but the module can only be accurately tested either with the PC-1-R CC tester or by a road test. Initially the setting per the FSM were a little harsh for the truck but after about a hour of adjusting the centering and the sensitivity setting its really close to being spot on. Its really hard to get the settings spot on, because the centering adjustment affects the sensitivity and vice versa. Plus not having roads that are flat, straight, and I can go 50mph on for any reasonable distance, makes it tough to get the settings right on the money. Its very sensitive, a incline of any normal degree will drop the RPMs and the speed, and the unit compensates as soon as it hits the preset MPH, I did notice that RPM's really don't affect the system, its the speed sensor and the mph that the system is reacting to. Well it works, even without the mystery harness, and all of the features are operational. Thank you guys for your insight and your help, with this conversion, hopefully someone who may try this in the future, will be able to push through the installation without having to go through my trials and tribulations.

Good observation, load might control or have an effect on the CC, the adjustments are pretty straight forward, the FSM has initial setting recommendations, which were what I had set the module to. I looked closely at the board. I don't see any burned circuit paths, loose bits, that are soldered to the board. I am no electronic engineer, so I don't even know what half the stuff is on that board(module). I do know that the three adjustments are potentiometers, some variable voltage adjustment for the rest of the board functions. Road test today to see if the load of the truck offsets the RPM acceleration.

Everything plugs in just as it should. I ran some additional tests today, tested the servo as per the FSM,seemed to do what its supposed to do. I also had the IS notes that indicated that early on some modules with specific date codes may have had issues, and were to be replaced. My module was not one of the effected units. I also checked the speed sensor per the FSM for AC voltage its supposed to be .9V @ 30mph. I came in a little high @ 1.05. Then I did the jack up the truck, put the rear axle on jack stands, turn on the truck, push on the go pedal to about 30 mph. Then I hit the ON switch, and pushed the SET button, everything engaged at 30 mph, BUT! accelerated to 55/65 mph, then dropped back down to 30mph, as soon as it hit 30 zoomed back up to 55/65, and it went like that till I hit the brake pedal. Did it again, this time it repeated and I used the off switch. So it turns on and disengages with the pedal and the switch, but now I have to figure out why its zooming up and then settling down and zooming up again. Without that PC-1-R cruise control tester, I am thinking the module might be the culprit. But I do know it works, without the mystery harness, just not correctly. Could the harness have something to do with the acceleration from the set speed? Or is the module fubar, and thats what is causing the issue.

Ohm, thanks for the direction, I checked connector C260, that's the connector that plugs into the white switch way up on top of the brake pedal, above the brake pedal switch. It has the servo dump valve hose attached to it. You push on the brake it dumps the vacumn out of the servo. I have the complete cruise control system, I just have a piece of the harness that I don't know what its function is. I have all the FSM's for the MJ. Its frustrating when you have pieces of the puzzel but no reference to which puzzel it goes to. Its obviously a Jeep part, does something with a relay and brake switch connects to a connector on a shifter cable, but I'll be damned if I can figue out what its function is or if I even need it for the cruise function.

Yep this is the one. there is no reference to the harness in the wiring diagrams

Looking for someone who has a Renix, automatic with a floor shift, and cruise control. I have a weird harness that I am not sure what it does. Also do you have a black plastic barrel on your shift cable with a white connector? If so can you tell me what it does? You can reference in the tech section, cruise control mystery connector, there are a bunch of photos regarding what I am talking about. Thanks

OK green connector, white with tracer PWR B+, feeds white connector to shift cable on one side, opposite side is light blue with black tracer, (something happens in the cable a connection is made some how) now power B+ is traveling to the relay through the light blue with black tracer, relay has (2) grounds, relay also has a light blue with black tracer out, that goes to the brake pedal switch. So what does it do, and how does it do it at the brake switch? Got to find someone with a Renix automatic with cruise control.

Well the cruise is out of a XJ wagoneer, the MJ was a non-cruise eliminator, both are automatics. You may be on to something,with the neutral shift position thing. The cable run is just like the one in the MJ with the exception of the black barrel with the connector on the cable. I would assume that a automatic MJ with cruise might have the same cable and maybe the same connection, but I have searched the schematics and can't find anything that shows a acc connection to the fuse box or a connector on the shifter cable. It does make sense that if the cruise is engaged, the servo would be keeping the throttle at a specific throttle position, with no engine load from the drive train, it would spike (rise dramaticly), this harness has a feed that goes to the brake pedal switch. If the relay got a completed circuit from the cable connection in the neutral position with a power feed from the ACC plug on the fuse block, then power would go to the brake switch, which somehow shuts the system down, so you don't over rev the engine?????

The harness did have a tag on it P05010002AA, T-7WJ2177AU3589 assembled in Mexico

OK, we are now close to the end of the cruise control installation. I have another weird harness that is part of the cruise harness. The cruise harness came out of an 88 XJ Wagoneer. The light blue with BLK tracer is connected to the brake switch, the white with BLK tracer, with the green connector came out of the fuse panel in the ACC plug in, the black wires (2) of them are connected to a brass ring terminal that was connected to the knee blocker metal brace, we have a white connector that plugs into a connector on a cable that I think has something to do with the floor shift release button. It is located on the floor under the ECM and runs up the steering column. I can tell because when I push the button on the shifter I can feel the cable moving. The final piece of this is a 5 pin relay, looks like it came out of a Ford its a mini, not a regular 5 pin. I have no connections on my shift cable or button cable. I have looked everywhere for a wiring diagram, but it was part of the CC harness and shares a connector with another blue/BLK tracer wire on the brake pedal switch. The Comanche wiring diagram shows no harness connection like this, anyone have a clue?

It appears that the wires from the stalk including the connector were removed from the column. The stalk has wire in it but right at the opening of the stalk where the wires would exit they are either cut or broken inside the small rectangular hole. Probably yanked on the cable and pulled them out of the stalk. Now I need to see if I can find an upper speedo cable. I have one but being as old as it is after very close inspection, the white plastic retainer is broken in two places. The upper retaining ring and one of the release legs, ATP & Pioneer were no real help and it appears that the Crown version is for a 90', which from the pictures looks a little different from the retaining mechanism on the current cable. I have (89)53004955 I have one Cherokee in the parts area, I may get lucky. we will see. Hornbrod, did you actually purchase a speed control package from Mopar to get that instruction sheet? Was it NOS? Or is it just the stalk and how to install the stalk, not the entire CRUISE COMMAND PKG.

Ok, thanks Schardein, thats what was confusing, I saw that stalk connector and the C253 connector and said there's no way that stalk connector plugs into that 4 wire connector but thats what the forum is all about, many minds, many experiences, and lots of answers. Thats got to be one of the strangest connections i've seen in a Jeep product, I am assuming that the stalk wire end is for the ease of installation down the column tube, but why the opposing end design? Weird. Thanks guys I just need to wait for for my E-bay shipment.

Thats the same drawing I have been working off of. The connector looks like 253, but I am not sure what the stalk connector is?

Here's the mystery connector

Ok, we are on to the next project on the wagliminator, got the complete cruise harness, vacuum lines, servo, and the interior harness along with the speedo cables and speed sensor. 1988 Wagoneer, the only head scratcher is the cruise stalk wiring. The stalk had the wires either cut or broken, and I don't know what the stalk plugs into on the interior CC harness. I have everything labeled from the removal even the special quad prong brake switch. But I have one connector that has four wires in the harness, and I don't remember it being connected to anything, and I think the stalk has 4 wires , but all the pictures of the stalk wire connector don't seem to fit the connector that I am wondering about. I have referenced the wiring diagrams, and I see the connector from the stalk to the module harness but no real connector views.

OK it took a little longer than I wanted but I actually got the last (4) OEM waggy headlamp bucket springs. 2 came out of Vermont, 2 came out of Colorado Springs. They were the last 4 in the US in Mopar parts dealers. The front clip is installed and it does look pretty cool. Installed my 850's in the Waggys front bumper so the location make room for the turn signals. I modified my high out put upgraded headlamp harness to run the low and high beam lamps, used the waggys headlamp connectors and soldered them to the relay harness. Everything works just like its factory, fogs on the dash switch, high beams the fogs go out. Once I got the springs in hand I realized that making a spring would have been pretty hard, they were specific to the wagoneer clip.

Well I'll get started tomorrow with the spring test, I am going to order one or a couple and see how it works. If it does I'll post the fix, with some pictures

Thanks for the picture Pete, that's a lot different then what I had pictured in my mind. Hornbrod, you may be right, with a little surgery it might work. What about heating it and reshaping it, just the lower tang part? Spring steel? I am sure that my torch can put enough heat to it, just what happens to the steel? Does it get brittle, or lose some elasticity? I am not a metallurgist. But at this point something close with a few tweeks is going to have to work. Unless I happen upon another Waggy Clip. Ha Ha

I was cruising Ebay last night and came across an interesting headlamp bucket spring for a 70's mach 1 mustang had a interesting hook design. What do you think?70-73

Thanks Pete, the parts diagram is not very detailed to get a visual on the spring itself. Specs on the length, hook configuration, length of the coil, diameter, would help in trying to make or adapt a spring to the application. I can't be the only guy out here that is missing headlight bucket springs for a waggy clip, someone has had to come up with a solution.

Pete thats great, now I just need to find the springs. I have searched high and low to find 56002220 which is the spring part number all I am getting is NLA. You got alternatives for the factory bucket springs? They have to be out there but based on the size of the bucket and the clip location a standard Comanche, Cherokee, or even a YJ spring is not going to work. Not a lot of Waggys in the middle of the Pacific Ocean. I tried some of the top Jeep salvage yards in the country and most say no luck.

I just picked upa 1988 XJ Wagoneer, going to swap out the stock front clip with the wagoneer clip. The problem is there were no headlamp bucket springs in the header assembly. The parts manual shows a spring #56002220, but I have no idea where it attaches to on the header or the bucket. Anyone one done the swap and have some pics of the bucket assemblies, with the spring installed? Is there only one spring or are there two per bucket? I am ready to disassembly, and reassemble but not without the bucket springs. Thanks

WTB a e-brake release handle with the little cable that goes into the release lever(fork)
