Tied up a few loose ends tonight.
My lamp reel is screwed in place on the firewall. There isn't much room on the passenger fender on a vortec truck, so it's beside the coolant overflow bottle, spliced into the stock under hood lamp. The reel doesn't quite reach to the back of the crew cab, but it's still long enough to pay for itself as I found out during the rest of my evening's projects.
The power seats are now working. On the fuze box there was an unmarked spot with no fuze in it, sort of recessed away from the rest and hard to reach. I put in a fuze and it made my seats work. Odd but I won't complain. One switch on both front seats remain inoperable though, I'm thinking they may be lumbar support.
Compass/auto dim rear view mirror and lighted visors are now wired in. The ports at the convenience centre have no power to them. Rather than troubleshooting this I just found an ignition switched wire and spliced into that. End result is the same, the visor lights work and the rear view mirror works as advertized. Now that I've done it once, I'm going to add my spare mirror in my '11 Grand Caravan since the instrument cluster lacks a compass (very few options in that van, most basic model even has a non foldable bench seat in the middle row).
Now I'm at a point debating whether I keep my overhead console or install my sunroof. Pros and cons to both, with no a/c the sunroof could be useful on the odd hot day, the console adds storage and a bit luxury feel. hmm, decisions lol
