Putting a 94 350 tbi in a jeep Cherokee. Wondering how to go about hooking everything up to keep it tbi. Any sugjections would help. I have the whole truck. Jeep has carbed 350 in it now

Pull engine harness and ecm, throw in an aftermarket fuel pump 13-14 psi, and you should be set. Keep the check engine light and obd port  wires intact, and reuse. That way you can check the trouble codes and diagnose issues if you have them

Hes correct.  use the entire harness with pcm.  I put a 94 tbi 454 and 4L80e in my 86 1 ton tow rig, works beautifully!

Would I have to run the gauges in order to do this or just the light.?

they sell a wiring harness with a lot less sensors and crap to run tbi. I got one I use to run t.b.i engines on my run stand. simple n easy has obd port no fuse box n just basic sensors that r needed to run it.

On mine we printed up wiring diagrams and built it off of that using what was needed to run the TBI computer and kept the existing 86 gages.  As far as speedo, that's a hole nother story..

I use a GPS for a speedo when there is not one in the truck that works, usually pretty accurate  ;D
