jeep HELP

[hoosier]

So i am not a "jeep" guy but I am doing an engine swap for a guy. (90 TJ i think, w/ 4.0) I pulled the wiring but the break sensor is connected through the main engine wiring harness. How do I go about taking care of that? I REALLY dont just want to cut it and remove the fuse I would rather do it right. Thanks in advance

Just for a little more information I am taking the 4.0 5speed manual and t-case (good running and is up for sale 106k on the clock) and putting in a TBI350 with, I think, a th400 and a np241. The engine is FULLY stand alone so the wiring is easy but the "extras" are what I am trying to get right.

There's not such thing as a 90 TJ. You're either working on a 90 YJ or a 97 to 2005 TJ. They are vastly different. I did a lot of wiring changes on TJs and everything was bulk headed off at the firewall, with disconnects on each side, which leads me to believe you're working on a YJ.

And if it's a 90 YJ it isn't going to be a 4.0 either. It'd be a carbed 4.2 or a 4-banger.

it is fuel injected with square head lights

It could be fuel injected from 1990, but it'd be a 4-banger. If it is a fuel injected straight 6 in a wrangler, it has to be 1991 or newer.

91 to 95 YJ then.

 

[hoosier]

sorry like I said I am not a jeep guy but anyways it is a 94 yj with 4.0

Back to your original question. There must be some way to get the sensor wire through the firewall but it doesn't sound like it's easy. Personally, if I couldn't dismantle at one end or the other and feed through the firewall in a reasonable amount of time, I'd cut and splice.
