Cooling/gauges/electrical many questions

[Snowstorm87MJ]

Hey all, it’s been a few years since i’ve even touched my MJ as it was parked when the drivers side unibody has begun to degrade as the passenger door throwing it out of commission in 24. Now that I'm in a bit better position of projects. And New Hampshire canceling inspection stickers i can actually drive and work on it and bring it places. 
 

 

1. this being said i have the dummy light cluster i also have a column shift 4.0 and i plan on doing the b pillar gauges for oil pressure and temperature. Looking back not having those was probably not a smart idea. Swapping the clusters is an option but because of the PRNDL is inside the clusters i figured easiest option would be b pillar gauges. Would the easiest sensor bung option be a later Cherokee thermostat housing? As it has the bung on the housing and the MJ does not or are they incompatible? Or any other mounting locations easier. I plan on replacing the rad tubes and thats why i ask about the housing. Oil pressure i assume can just be tee’d in a three way on the oil sensor hole? 
 

#2 when i first got this truck in 2019 the column was a victim of the previous owner family friend. took the angle grinder to the column to cut the ignition as it was royally locked up from sitting 20 years i did not have the time as the house was sold and it was either tow it or its going to the junkyard. An oem column shift column would be nice but i also don’t want to spend 400$. The barrel was jb welded and thats how i’ve been starting it for years. Looking for ideas on a custom ignition switch that isn’t intrusive. Will probably plate the gaping opening on the column. 

 

#3. My wipers worked but the intermittent function occasionally worked now after blowing the ECU last summer and replacing it i no longer have wiper functionality at all. Not sure if it’s related or just from sitting. I know the module was probably crap but the lo hi and wipe use to work. Not sure where to start there. (I also have a manual washer toggle as that died too but way earlier) i did do the ground clean up but i suppose thats 4 years old at this point.
 

 

#4 LED turn signal sizes for the front? I went through like 4 brands last year and can't find bulbs that fit in the housings correctly. 
 

i plan on doing k suspensions terminal upgrade. The battery wires did miracles on my XJ. 
 

 

#5 it’s an 87. I’ve only ever seen the seatbelt and brake warning light pop up on the side dash. 4WD never worked and i don’t have a windshield washer sensor. Is there any other warning lights that i should have that i don't? 87. Dummy lights and pretty base model besides the 4.0. 
 

I have rust free doors to throw on and ripping pans out again to do unibody work yay. 
 Sorry if this is the wrong place for this!

Yes, the cherokee thermostat housing will work just fine and give you the temp sensor bung you need.

Oil pressure you can T in if you want. Just use copper line and not the clear plastic stuff.

A cherokee column should work just fine. Or you can source a used one from a yj and use it as parts to put your s back together. Its a gm column that was used across multiple platforms.

The wiper delay module is probably bad. Likely just coincidental, more than likely from sitting. The module has a lot of capacitors in it. Ive been slowly trying to work out a repair or replacement solution for that.

You can bypass the module and plug the wires together or just leave it be and hope you find a good module from a xj or yj. 

 

#4 LED turn signal sizes for the front? I went through like 4 brands last year and can't find bulbs that fit in the housings correctly. 
 

The side markers or the lower lenses?

Thought the side markers were 194

I can't remember about the lowers.

The bulb for the 4wd indicator could be bad or the vaccume switch on the passenger side of the firewall next to the blower motor could be bad or not seeing the vaccume it needs to trip the light.

You can fairly easily add a windshield washer sensor, but you would need the tank and sensor. 

I think they had shift up lights for the manual mjs, maintenence light, check engine.
