Work on the truck continues. I'm simultaneously working the window issue and working to add lights to the roof (the lights are more for Africa, but poor visibility was a reason I stopped driving early in Ukraine on the last run).
The windows are taking some work, and I'm glad I got the back one fixed first as this circuit is slightly more complex. The reason is, we're going to be needing 4-relays total. Two for the driver's window, and two for the passenger. And when it comes to the passenger's window, there are two switches that operate it. I'd like to keep them both working if I could. Plus I'm kinda stuck with the factory wiring inside the switches. It's not like I can just swing by the hardware store and snag a new window switch. But enough excuses, let's get crackin!


I think I got a good circuit going and in my head at least, it looks like nothing is going to catch fire regardless of switch position. Next up is to get access to everything in the truck (and of course, working day shift now, that means 4am wakeups)


With the back window, I could easily hide the relays behind interior trim panels. I couldn't find a similar spot in the cab for the front window relays, so I went under the hood and found a spot on the firewall:


Except I don't want to punch 100-holes in the firewall (4ea for relay mounting, and then we need to ground each one), so I decide to fab up a quick mounting plate from some scrap aluminum I had laying around:


I have some steel stock (angle, and flat plates) that I can clamp up to use as I don't have a finger brake in my garage. So that's what I use to make the bends I need:


oops. that's not good.
I got it bent, and RIGHT as it hit the 90-degree mark I broke it...
Ok, no prob. Maybe I can add a spacer underneath to make a bit of a standoff. Then I could just make a new mount, drill 2-mounting holes, and use the standoffs to hold it away from the firewall a bit:



Nope. I'm not happy with that.
I really don't like the home-made look of the plate ends, and the stand-offs don't hold it up as high as I'd like...
Ok, so scrap plan-a and plan-b. What's next?
Well, I do have some stainless scrap. It's a bit thinner than the aluminum, but it should bend the way I want it to.
here goes:




Ta-Da!!!
I'm happy (enough) with that one. Next up, I gotta hit the coffee can to find some hardware to mount everything to where it needs to go:


Done!
Next up, we mount everything to the firewall and wire it up.
