Hey. I have found many threads about 4cyl to 6cyl swaps, but have not found the info I need.
To start I am preparing to swap my 90TBI 4cyl/5sp with a 92 4.0/5sp. My donor driveline came from a 92 YJ. Unfortunately, I do not have the engine wiring harness or the ECM for this engine. Can I use a wiring harness from a XJ as long as it came from a manual transmission jeep? Which years would work best? How will using a XJ engine harness affect the rest of my YJ wiring. Will my fuel pump be reusable?
Thanks in advance for all your help and suggestions.
