I am installing an after market turn signal switch in my 61 Apache. I have the schematic from the manufacture. The schematic shows 2 of the seven wires going to the flasher but it also shows a hot wire going to the flasher. In my mind there then should be 3 spades on the flasher yet everyone I have seen is only two spades/wires. Can someone tell me how to wire this into the flasher please?
