So a test drive revealed a few things:
1. Speedo works flawlessly! No bent needle, no jumping around, and speeds still indicated below 50km/h. Win win win!
2. Tacho works as soon as you start the truck, not "as it warms up". Excellent.
3. Hub lock, 4wd and E-brake indicators and dash lighting is all now fully functional. What LUXURY!
4. Steering is literally tightened up. Loose and nasty wheelbearings = bad. New bearings and grease = good.
So now it's on to the projects... starting (and never ending) with electrical.
I gutted my whole setup and am starting from scratch. I picked up a metal box from Amazon (made for distribution panel?). Quality is meh, but I think it will work for my needs. Plan is to mount devices on removable back panel, and then put the battery (on tray) in the bottom. All is accessible via a lockable door. This will mount forward of my stacked drawers, and I can access it from LHS back passenger door. Here is how it is shaping up so far:
I've also begun the task of adding electric trailer brakes. While I'd love to have a locker controller in this spot, the dial for the RedArc controller is a nice fit as well. I had to enlarge the hole to 1 inch, but then the control dial fit right in. It's easily accessed while driving, and can be seen without having to look around the controls. The control dial was the easy part, so more to come on this one...
To the trailer wiring itself... 24v vehicle to 12volt trailer requires some fiddling. So I landed on this little unit, which will go in line with my flat 4 wiring (coming out of a Reese control box), and then plugging into a 7 round harness which will exit from the rear bumper. I was aiming for a different plugin site, but anywhere I could fit it would hang down and ultimately get freed by the terrain. So I have a large hole in the bumper awaiting a socket. If this doesn't work out, the backup plan is to reduce my side exit tail pipe down by an inch or two, and re-route it to for a snazzy bumper exit exhaust. That'd look cool right?
Finally, I pulled out the cheap/ crappy center armrest I got from Etsy, and replaced it with something even cheaper! LOL./ I grabbed a Plano ammo can the last time I was passing the army surplus in Idaho. It seemed about the right size. Then recently I found an armrest cover on Ebay for a Honda Civic. Put the two together, and I have a 50 cal center armrest! (Yes, I blasphemously bolted it through the OEM console lid, but the holes were already there from version one, so less guilt this time around). It's khaki/green, but the topper is gray and mostly fits in with the aesthetic, which is to say there is no real aesthetic. This is purely for function. Form left a long time ago. But it feels solid yet comfy under your elbow and is about the perfect height.
