I removed the toolbox and rack, took the rack to my work table in the yard and fought the wires through it, with a flexible wire fish.
Tested, connected, tested, re-tested, then re-installed the rack and the box.
I had help, from wife, to move it back and forth and guide the wire fish.
The real hard work can now begin, connecting everything under the truck, into the junction box.
PO wired wrong colors for the trailer and I connected to them.
Now I get to test everything under the truck. Not much fun, crawling in and out, while switching and testing, but that's life, when you don't have a willing helper.
