Rewiring my Jeep, Part 4

I spent Saturday and Sunday working on the Jeep wiring project. Saturday was mostly spent figuring out where to install my new stereo amp (I chose the center console after looking at multiple options). I had to get a step bit for drilling holes in the console for the wires to pass through. I’ll probably need to add one or two more for cooling. I made an existing hole in the dash a bit bigger to run the 12v+ for the amp through. I do have a new battery shelf on order as well.

Next I noticed that the engine coolant was leaking out around the new coolant sensor I’d installed. Definitely not a good thing, so I wrapped the fittings in PTFE tape (good to 550F) and re-installed. (Fun note, coolant expands when cold….)

Then I finally started on the engine side rewiring. I realized I’d made a couple mistakes in pulling the wiring. I should have just disconnected the pigtails for the brake warning indicator and transmission 4wd & reverse indicators. I ran the old pigtails back, but had some trouble, especially with the brake warning indicator. I may need to replace the pigtail later, which will be interesting. They’re very hard to find.
I also should have taken a lot more photos on the general routing of all the wiring on the engine side. I’d only taken photos of each of the connectors. I’m having to take some liberty with deciding how to run the new wires.

I got the new Ignition Control Module installed, the harness for the ICM to coil & distributor in place, swapped out the old broken distributor connector with a new one (had to splice it in). Ran the headlight wires, but waiting to put the lights in until I get new housings (ordered) to replace the broken ones that were there.

Most of the driver’s side of the engine is done. Remaining are the starter, starter solenoid, alternator, and battery. I’ll have a number of extras to clip and heat shrink, too. I’m waiting to do that until I’m done and verify everything is working, though.
The previous wiring for the starter solenoid and alternator didn’t match any diagram I can find for any for it, so I’m following the manual and matching what’s documented as “right”. I do have notes of what was there previously in case I have issues, but I think it was a bit of a hack.

While I was working on things, I pulled the speedometer cable. Since I’m using a GPS based speedometer it was no longer needed. To cap off the opening in the transmission I just cut the speedometer cable as close to the fitting as possible, then closed the end off with some JB Weld.
