Ya it's converted to a 6 cylinder 4.3L carbureted engine. Who ever did the conversion jacked up the wiring pretty bad. Hense the meltdown haha. But with not using a harness I know exactly which wires go where so it will be easy to diagnose problems. So far it's cost me about $300 which is a lot better than $540 for the harness and fuse box. And ya it's been very time consuming and tidious trying to understand schematics but so far so good haha. And iv got a Haynes and it helped a little but it was more for repair not for refabbing.
The stock jeep is a 4.2L inline 6 and no fuel pump. If you have a fuel pump it would mean that you probably have a throttlebody with a single injector or multipoint injection. Can you please take a pic of your engine and post it?
If it is stock wiring under the hood. It could be a wiring harness kit. If it is then color references don't mean a thing. You will have to do it the old fashion way. Is the interior harness still in good shape?
The harness from engine to ecu is still good but I completly scrapped the one from under the dash to fuse box and fuse box to engine bay. I maybe could of salvaged the one under the dash but the guy who did the wiring before had already hacked in to it quite a bit and I decided to get rid of all of it. I guess my question now is which post coming out of the ignition switch goes to the battery and does anything else need to get wired into it besides an inline fuse?
Ya I'm just gonna wire in what I need. Battery, alternator, ignition coil, ignition switch, fuel pump, starter, and fuse box. Then little stuff like lights and radiator fan will get run to fuse box. I'll draw you up a diagram of how I'm going to run everything and post it once I get off work. Then maybe look can look it over and critic it?
