the headlight harness and what all the wires coming from the back go to. i already know what a few wires go to like the hi beam, low beam, corner markers, and the power supply.

but there are 2 gray wires coming from the same terminal, and a yellow and black wire coming from the same terminal as the low beam wire.

halp please...

Here's a pic taken in progress of my 1st harness.

Ran a new heavy duty cable, within a sheath, along the line of the factory cabling. Two relays mounted just behind the front panel ( on the chassis part that runs back towards the passenger cabin). Then individual wiring to both dip and main bulbs, wires all in a loom I made up. I used factory style plugs and can revert the whole within a few minutes.
If you wanted to be really extra safe it would be possible to relay the battery cable, at the battery, switching on the relay when the ignition is switched on.
Well worth the effort.

I do all the wiring under the hood, including picking up the high and low beams signal.

(I used an old headlight bulb on one setup, and broke away all the glass. Soldered onto what was left of the metal terminals, so I had a plug that I could insert into the stock headlight connector. No cutting ANY stock wiring then, as I plugged into where the stock headlight bulb would have been to pick up the hight and low beams signals to trigger the relays..)

Look at the connector in the upper left, to see what I mean..
