87 Comanche 4x4 swap

[DirtyDeeds]

ok i have a 96 xj sport 4x4 with the i6 HIOutput the toyota auto trans that I'm having rebuilt and a NP242 tcase, the body is rusting out on me.

I'm picking up a 87 2wd manual Comanche this weekend and I'm planing on swaping EVERYTHING out of my xj into it. Engine, trans, Tcase, both axles.

i know everything is direct bolt up and ill have to have a new drive shaft made, i did a 2wd->4wd swap a few months back on some xjs one auto and one manual with a friend, but they were a 96 and a 98. so we didtnt have a prob with the issue I'm concerned with 

my question is what do i have to do to put my OBDII engine in a OBDI truck?
i know ill have to swap ecu's but what else? 
any other problems or concerns yall think i might run into?

a lil help would be nice as ima start taring into these 2 in the nest few weeks

 

i posted the same thing cherokeeforums mj section and tbh i havent goten much help here's the link to my original post

The 87 is pre-OBD1.  

 

There is a write up in the DIY section on putting a HO (91+) into a Renix (87 - 90).

You will need to swap the dash and engine harnesses. You will also need to figure out a way to make your fuel sender read correctly. Not to mention 96 uses a 1 year only fuel system.

Well in that case I'm hoping ican get the renix engine to run good then ill only need a flex plate for my auto trans and figure out how to wire the tcm and a tps that will work, any ideas? Also if I do that how will i wire my 4x4 indicator lights in the Comanche gage cluster?

[shelbyluvv]

If you are just swapping the engines,the renix to obd-I guide will work. If you want to keep the everything on the engine and run the obd-II you will need to swap harnesses.

[Wiggilez]

The rear axle isn't bolt in, you need to moving d the spring perches on the alxe.

you could also swap the engine and trans WHILE keeping the renix system intact. just have to swap the flywheel, distributor, intake and belt accessories.  I have a renix engine and tranny in my obd1 MJ

UPDATE ok the engine and fuel system in the Comanche is trashed and un-usable so it looks like I'm just using everything from my cherokee.

 

any one ever pull all the wiring harness, ecm, tcm, gauge cluster well pretty much all the electronics and swap them to another jeep who can give me some pointers?

 

this is my donor cherokee and the comanche everything's going in

I didn't scroll completely, and got really confused on that red truck and Comanche.

I don't think ive ever seen rims like that.... I kinda like them, their like an outlaw 2 but then not really... wonder what they would look like with center caps

from what i understand they are factory alloys, they came on the Eliminator and Pioneer. so I'm thinking its posible mine started out as one, is there any way to check the vin for it?

[mikekaz1]

But those are different? The red jeep lugs mount flush with the rim. Those are the standard ones you see. The jeep version of the outlaw 2s. But that black one the lugs are recessed. Like as if a center cap went over them.
