Help with a couple of questions

[johngus]

I am in the process of converting my 88 MJ from a manual (BA10/5) to an automatic trans (AW4). I removed all the parts from a donor 89 XJ that I owned. My questions are the following:

 

1. I am replacing the wiring harness to accommodate the TCM. Do I have to install the ECM from the donor or can I use the one currently in my MJ?

 

2. If I have to replace the ECM, the donor vehicle had ABS, will that affect my swap at all?

 

Any help is certainly appreciated.

the ECU is separate from the TCU, shouldn't be necessary

 

you WILL need the throttle body from the other jeep with the kick-down cables and TPS attached if you want it to work like it was built that way.

Thanks for the info. I salvaged everything I thought I would need off the XJ including the throttle body, trans crossmember and flexplate.

what are you doing with that ba10?

nice, I'm planning a swap from the BA10 to an AW4 myself soon, but i plan on using an http://www.awshifting.com style shift kit, cause I'm not sure i want to deal with all the wiring stuff... i might later on if it gets annoying.

you know, I was thinking, an AW4 swap with a column shifter and that 4 speed arcade style shifter in the center console would be pretty freaking sweet.

I am going with the stock shifter for now. I also salvaged the buckets and console from my XJ, I'm going to see how they fit up. The BA10/5 will be available soon, I want nothing more to do with it once its out.
