Just posting some info in case any future reader comes across this.
After installing the 7G LED bulbs from Sirius, with the headlight switch in position 1 (parking lights only) the high beam portion of the LED bulbs would turn on, but not at full power. I measured the voltage at the high beam socket and the ground and got about 6v. With the headlight switch in position 2 (headlights on) i was getting full high beam. Flicking the high beam stalk, i could hear the high beam relay click but no change in the bulb operation.
This left me scratching my head for a few hours. I was thinking bad LED controllers (unlikely as both would have been bad), or possibly something strange with how the headlight relays on my aftermarket fuse panel are setup.
So the issue was this, the fuses for the high beams have your incomer from the headlight switch and on the outlet side the wires going to your bulbs. Also on the outlet side, is a wire that goes to the high beam indicator, and another wire that cuts the foglights out with the high beam on. This wire is not on the wire diagram in the Bentley manual, so it wasnt until i actually looked at the wiring did i realize what was happening
.
So the fix for this is to ground that wire for the fog lights somewhere on the chassis... this will result in your fogs staying on even if you activate the high beam. I dont have the full wiring diagram but i am guessing the fog relay is grounded through the high beam wiring circuit. When you hit the high beam, 12v goes through the entire circuit cutting the fog light relay out.
Anyhow here are some pictures;
The 2nd 7.5amp fuse from the relay you have a blue wire, white with blue and a white with brown. The white with brown is now connected to the twist connector and is grounded to the chassis lug next to the fuse panel. See next picture.
The driver tucks nicely into the headlight bucket.
You have to flip the heatsink around and position it as shown... others mentioned this in previous posts. It fits just barely in the headlight bucket.
Nice and bright light... much whiter than the halogens.
