Wayyy back when in 99 when I installed a 5.0 in my YJ, I bought a street rod harness, still have the original harness. It came with a very good manual. I grafted the harness back into the jeep wiring after I removed all unnecessary wiring from the other engine and jeep, took 2 days but everything works, gauges, idiot lights, check engine, etc. I also sent a copy to in2deep when he did his CJ-7. I would surely look around there are several good harness manufacturers out there, just make sure it has good directions/wiring diagrams.
