Report "Hi ,I have a 1973 airstream ambassador and cant find a wiring diagram.I have no brakes on the trailer. I replaced all four brake magnets and wired them the same way they were wired. I burned a fuse on the tow vehicle and want to check the wires that go from the tow vehicle to the trailer and need a diagram. Is there a wiring diagram I can look at on line? Thank you Mark"
