I've done it again - disassembled and thought I would remember. Can someone confirm the wiring on the tabs of a '66 horn relay. I have a single black wire connector and a pair of greens on a single connector (green to horns) With the horn relay mounted on the radiator support - there are 3 connecting tabs from underneath. Positions are LF (which is hot -so doesn't make sense to put green horn wires there), LR and RR. The AIM does not show the detail of what colors get connected to what tab. I will put this in my AIM from now on.
Thanks for the help, Krister '66 SS L34 #'s
