Here's my problem, the flasher unit that I have only has two wires, blue and yellow, for each side of the high beam. Of course there is the white wire (12v), green wire (ground), a red wire (12v Switch), and a black wire (parking lights) for nighttime disable. The diagram shows only to cut one wire and splice the blue wire to the driver's side and the yellow wire to the passenger's side. In this thread, you referenced two separate wires. Can you explain the wiring diagram in detail about those two wires in the harness? Does each wire power each high beam? Or does one wire power the low beams and one wire power the high beams? I had this flasher unit hooked up in my Ford F-150. It was a one wire cut with the blue wire spliced in to the driver's side and the yellow spliced in to the passenger's side.
