4.0 swap

I just installed a 99 Cherokee 4.0 into my 88 Wrangler. The engine starts right up but then stops within 5 seconds. Is this because of the sentry key security system? If so, how do I bypass this? I also can't get the OBD II diagnostic port to work. Does anyone know how to hook the port up? The check engine light also needs to be hooked up. Does anyone know the color of the check engine light wire in the 99 Cherokee wiring harness? Thanks!

Read this thread. It might help a little


Oh wait. That was the thread tittled "DO NOT POST VEHICLE SPECIFIC QUESTIONS HERE" I guess you missed that one. Try the Jeep section and Good luck
