Well, the solenoid wire goes up into a factory wrapped loom under the intake and throttle body and up through the firewall behind the dash. Any better way to check this stuff without taking half the dash apart to trace it? I can take the solenoid wire off the starter and just check the voltage applied to it when I hit the key- never has been suspect as I've always got 12.4-12.7 volts.
As far as the neutral switch goes, I can only start the truck in neutral and park; no other gear selected lets it start. I thought this would signify it as working properly, do I need to do some type of continuity check on it as well?

Hope Toyota takes this starter back!
