HELP: Headlight switch triggering STARTER!!!

I have to tell you the "fix" makes no sense---makes me wonder if there isn't an intermittent and all the shaking of wires opened the cross connect. There is no ground in the start circuit in the passenger compartment. The path for the starter relay is ignition switch-----yellow start wire-------out into the engine bay-------through the seat belt reset---------to the starter relay-----through the relay coil-------down to the transmission--------to the neutral safety switch.

That wire would have to be picking up power somehow from the headlight switch..........which has no obvious connection
