Today I completed installation of the Wig Wag Flasher. Attached to this post are an enlargement of the Unitrol connection diagram and a photo of the flasher installed in 0327.

On the '82 Mustang, the low beam headlights have two filaments. One filament is for low beam only, the other filament is powered up when the high beams are on. As shown in the stock wiring diagram, when the low beams are on, the headlight switch connects power to the low beam filaments but cuts off the power to them and switches power to the high-beam element in the low beams plus to the high-beam filaments when the high beam switch on the steering column is clicked on.

Once I located the two places CHP Motor Transport had spliced in to the wiring harness, the next task was to figure out which side went to the headlights and which side came from the headlight switch. Cut the splices, turn on the headlight switch, then check voltage at the wires. The side with +12V is coming from the switch in both cases.

I used #4 self-tapping sheet metal screws to attach the flasher to the sidewall, using the original holes. Self-tappers ensured a good ground connection for the case of the Flasher.

The +12V input wire (blue in the photo, as in the CHP wiring diagram) would be connected to the WW terminal on the back of the Federal CC1 controller. I don't have the CC1 installed yet so I just touched it to a voltage source to test. The wig wags worked perfectly!

Another good day for 0327.
