We have done alot of motor swaps here in the shop but we have not worked on to many TJ. We mostly work on older YJ's,CJ's and build comp. buggies. I have a customer that is wanting us to swap in a Voetec V-6/TH350/Dana 300 into a 97 TJ. Not sure what year the V-6 is yet, he has not bought one yet. Just wanted to see what trouble you guys have ran into, wiring wise. He can handle most anything just thought I would ask some of you that have already when this way with your rigs, I am sure you know more about it then I do at this point. I am sure he wants to use his old gages in the jeep and we have dealerships for a couple different wiring places. Tell me what you have learned and what not to do. Thanks a head of time. M

Kelly at 4wd.com did that to her competition Jeep. Might want to head to their forum and talk to her. There was a really good write up on there about her Jeep at one point.

We pushed my 4.2L two inches over to the passenger side in my TJ, used a Painless GM column wiring kit and a Howe harness. Howe's reprogramed junkyard computer was found to be rotted out causing all sorts of sensor fits but the stock 4.2L computer from a small 2wd Blazer I replaced it with works just fine.

I've been told converting the stock throttle body harness is a good way to go due to the quality of the connectors and huge cost savings.
