I want to install a 789 Delco Remy Headlight Relay on my 39. It has a fuse holder with a terminal at each end of the fuse holder. Two other terminals coming off the side of the relay. I have no clue how to wire this up. Anyone have a wiring diagram for this unit? I believe the part number would be 1116789.
