Someone mentioned a wire tracer in a post. Did a search and found this would be quite a handy tool for our application. It won't tell me what the wire is for, but where it starts and ends, which is half the battle. Today I unhooked the harness from the rear of the bus and drug that end to the drivers seat where I sat with my MM and step on peddle and turned signals and what have you. I was looking for a place to ground a wire and found I could hook it through the hole of the key, closest convenient spot.
Question is there is a wide price range for tracers. Is this cheap one suitable for our needs?
