Did the accessory wiring today. CB radio and an absolute mess of USB ports and 12v jacks.
Since it isn't really a permanent install, I decided to eschew dicking around under the dash and just run 12ga marine cable (so rated for salt water, oil, gasoline, diesel, cold, heat, abrasion) from the battery, down the fender, exit near the door hinges, duck inside (crushed in the weatherstrip) and then mount all this shit on the passenger side dash.
Of course, on the passenger side, there are no convenient cable-sized holes into the fender. So I had to make one. Remove the washer bottle and cue the step drill to drive a bloody great big hole into it.
Lesson: That bottom hole doesn't actually go into the fender. It goes into some effing void cavity, presumably for smuggling whatever drugs fueled the Chrysler engineering teams. That UPPER hole actually goes into the fender.
Then cut some MDF and drill some more whacking great big holes in it. Add a ratsnest. Use a scrap of MDF to make a junction plate. It's probably safe, right? Rebuild that plate 95 times because you keep connecting the wires wrong. Heatshrink your connections.
Cram it into the napkin tray thing.
The wires routing out the front are the marine cable and the radio power wire (the radio is mounted on top of the dash)
Fit and finish are excellent.
That blue LED is going to be my enemy (that's a USB charger with a blue LED voltmeter)
I didn't take a picture of the completed battery area, but it's got a giant coil of leftover marine cable sufficient to relocate this shit to the center console if it doesn't work out ergonomically.
I bunged the radio to the top of the dash pad with drywall screws. It weeble wobbles around something awful, and I'm sure somebody's gonna be pissed that I put holes in an otherwise pristine dash pad. But I legitimately couldn't find anywhere else to mount this that wasn't going to take a day of careful cutting and fitting. There is virtually NO empty depth in the dashboard of this thing.
Brakes and final finish work tomorrow. Depart for rally Monday night. Rally Tuesday.
