Basic trailer wiring for a guy that's definitely not smarter then a 5th Grader.
OK no diodes. Keep in mind that 1) the toad electrics are not
involved. I put two bulbs (drilled thru the back of the light
fictures and glued 'm in) and ran wirers to them. It would be like
having magnetic lights stuck to the car. No connections made to the
toad accept a ground. 2) everything works when the car is connected
to another vehicle. The problem is in the bus. It has to do with
connecting the hot lead from the brake lights to the hot wire from
the turn signals. It's something stupid simple that I am overlooking.
Or plain don't understand. I wonder if its the flasher unit? It has
enough power to flash both the lights on the toad and the bus but
when you add the brake it shuts down. Hmmm
