I'm trying to prepare myself for the wiring of the body portion of the 5.3 swap...like the lights, signals, heater, ignition, wipers, etc. Unfortunately, I wasn't the one that took the harness out of the vehicle. The PO did all the work.
Here's what I'm dealing with. This is the main harness that plugs into the firewall side of the fuse box.
The right hand branch appears to be for the head lights and signals. I also have another harness that I know
is for the head lights that should plug in here. That one is pretty much still together and facory looking.
This middle branch definitely goes through the firewall and back inside the vehicle. Is this for the gauges or is it for all of the interior wiring? The PO cut quite a few wires out of it and I'm thinking he may have done that because he wasn't sure how to get the harness out of the vehicle if he didn't. Unforutnately I don't have the jeep here to see where it would go.
The left side branch looks like the old engine stuff. I'd like to start removing that part of the harness this weekend. Is there anything in here that I need to keep? I see a couple of power leads. I'll probably keep those. Are they for the alternator? What about the starter relay? Is that the rusty bowl looking thing?
These wires are in the middle of that same branch. I'm not sure what they are for.
I do have the pinouts for the firewall plug. I'm hoping that will help me along the way.
