I'm wiring a 29 dodge, using an early eighties dodge motorhome 360 and 727, got the stock relay and starter, but don't understand fully how they work. I'm in need of a simple diagram and explanation of how the relay works. The starter has two lugs, one heavy for the battery cable, the other very small for a smaller gauge wire. The relay has two push on connectors, one heavy terminal for the battery cable and a smaller, but heavy screw on type terminal. I can't supply pics, the car is miles from me, going to his shop to finish this thing. Otherwise, the car, steering column and engine are wired like a chev. Can you help?
