Haines manual question.
I have a Haine's manual for my truck thanks to my brother in law. These things are god sends and I've owned one for every car I ever had.
However, as is often the case being english, somethings are named differently over here and that adds a little confusion.
Looking at the key for the wiring schematics (I can read wiring schematics just fine) I see a reference to 'tracer' or 'tracer wires' and I'm not sure what they mean by that. I am guessing it's a return wire on a circuit or component like when you have positive, negative and a neutral return?
But if someone could explain what they mean by 'tracer' I'd great appreciate it.
