01/22/2018 Rear electrics and light
Next on post trip suggestions list was power to rear of car. Had a box of components months before that were sitting around for a planned wiring run, when I was last in CH, outfitter Marc suggested welding cable as good quality and flexible for any amount of power you could ever need in a car.
Used
>2 ga welding cable, 25' sections of red and black ea.
>sealed marine lugs
>marine heat shrink
>0.5" marine loom (whatever was highest heat rating, found at marine store)
>Super 88 electrical tape
>zip ties
Got under the car three or four times measuring an exact, and then more generous run length to account for stretch, flex, pulling on the wire, then cut to size, approximately 15 feet of cable.
Fit sealed lugs, used a hydraulic crimp tool, then put shrink wrap over that, ran all the wire inside loom, and taped the whole length shut. After that it was just running the cable under the car, and securing it. I did have to drill one hole at the very rear of the tub in one corner, felt bad about it but there was no other way to do it and it can be capped if everything is removed.
Cable is fused at the battery with a 100a ANL, and where it comes up into the rear of the tub it enters a manual switch box that then sends power to a blue sea 6 slot fuse box. Both fixtures are just velcro'ed in and can be removed. The hole it passes through does need a grommet... working on it.
Wired in some pigtails as plugs for any future item. Plugs are deans. Easy assembly/disassembly, lighting changes, etc. Bit of a pain to solder (still learning to do a neat job)
Did a wiring run from fuse box to the inside ceiling, a sealed section with plugs on each end, for a dome light.
The larger black bundle is for the rear flood/reverse lamp
Dome light actually a map light with a red filter, was a good price on another order of items. If I want it somewhere else just unscrew the mount and unplug from the loom right there, move it somewhere else.
And before anyone says "why not just use a billion LED strips?", I want it simple, small, and for now minimal power draw. This 6 unit fixture is just fine. I have several types of LED strips and am slowly experimenting with them for other purposes. "Better is the enemy of good enough".
Bonus, top right is a field expedient that has worked quite well. Just a hammock hanging strap zip tied to the roll bar, hang dry bags and rope bags, rigging, gloves, etc. off it. Out of the way and away from leaky windows in rain storms.
