Wire Colors at Headlight Switch

OK, well look

The dimmer switch is a simple, one pole, double throw switch

Headlight power comes INTO one terminal

Power goes OUT one or the other terminal, and when you mash the switch, these two terminals reverse, IE the terminal which had power goes dead, the other terminal becomes powered

High and low beam power go from the switch, THROUGH the bulkhead connector

Power branches off from the HIGH beam wire before it goes through the bulkhead and goes up to the cluster "hi beam" indicator.

So if you have low beams, the light switch is OK, and at least 1/2 the dimmer is OK

If you have a hi beam indicator light in "high" beams, then the OTHER half of the dimmer is OK

If you have power on both high and low beam wires on the engine side of the firewall, then the problem HAS to be in the engine bay harness, grounding, sockets, or "it's possible" that the high beam filaments in both lamps are burned out.

Your explanation is clear as day!!

But is there supposed to be a light green wire on the bare terminal I have at the headlight switch??

***Also I forgot when I was testing last week at the headlight terminals I have power on the Violet with low beam and then when I hit hi Beam it goes to the red wire. Does it need to be hot on both wires????

Both lights were changed last week also, and yes the Hi Beam indicator does come on in the dash.

I'll get the meter on the firewall connections today to see.

Thank you
