So I'm bypassing the rear window relay on my 89 4runner and running a fusible line off the battery, but I got a few questions here though. The OEM switch is dead, so I got a new switch and ran it from a charger to the window motor and everything works fine, the problem is my rambunctious dogs. I can see them hitting the toggle switch (it doesn't matter where I put it in the cab) and running the battery dry. So I'd still like it to run from the ignition so the power's off when I'm gone. But when I test the voltage at the original lines, what I get is
8.9 vdc at R-W
8.9 vdc at R-Y
and 8.9 at Blue-R with neg. at ground.
So none of the existing is going to run the motor. AND, when I tried one of the combos the head lights went out, there was, what sounded like an electric motor running, then dying, when I tried to turn them on again.
This is my first time diving this deep into Toyota electrical, and I need some help. Cheers.
