HELP! Need a wire I can tap (for relay) only when xenon highs are on

Obioban · 01-16-2006, 09:30 PM

Anyone know where one is in the car?

Are you trying to wire your garage door opener to your high beams. Do you have xenon high beams i don't think they make them cause it takes a few seconds for it to reach the right brightness.

no, I want to make my halogen highs (inner bulbs) come on with my xenon highs (outer bulbs). I'm going to wire a relay but I need something to trigger it off of.

Post # 19 might tell you which wire to use...

nope, that just tells me which powers the headlights, which I already knew.

Sounds like you need to tap to the bi-xenon shuuter trigger. My xenons were a retrofit so I can't tell you the wire colour, but you are looking for the center pin of the smaller three pin connector going into the OEM ballast (this controls the shutter mechanism. It is positive trigger and should work fine with an extra relay load, but be sure to reverse-diode the relay to prevent spikes.

BTW this is the way I wired my high beam setup and it works great. Only problem is I believe you will loose flash-to-pass unless you get a bit creative with diodes.

If you just tap the high beam wires you don't lose the flash to pass. Mine is wired to that the shutters are only active if the xenons are powered. So if the headlights are DRL only the flash to pass works as it normally would.
