So in my last post, I put electric brakes on my trailer (along with the new axle). Those won't do much good unless I have some way of telling them to brake when I want them to while I'm driving. Hence, I installed a brake controller in my truck over the past two days.
2000 Tacomas didn't come with a factory tow package, so I had to dig around under the dash to get all the right wires to the controller and to the plug in the back.
While I was at it, got all the wiring in place for the trailer-mounted backup cam, with a switch in the dash so I can manually switch between the truck and the trailer backup cam.
I also got fed up with all the slapdash chassis grounds I had going on at the rear of my truck, so I ran a 10awg wire directly from my battery to a marine-grade bus bar, and grounded everything to that. My cam no longer flickers when I have turn indicators on.
I tested the brakes today and they seem to be doing a fine job of stopping the trailer. Probably a bit more tweaking I need to do but for now, I feel good that my trailer isn't going to push my little truck through an intersection.
