Do i need to change any wiring?

dastrix · 01-01-2008, 06:11 PM

Hi Guys

My car has self leveling, auto halogen headlights. I am fitting OEM Bixenons that my car came with if you ordered the option.

Does anyone know if the wiring is a straight plug/play between the Halogen/Xenon ?

The Xenons I ordered are complete, all the bulbs, ballast and so on (All OEM BMW stuff)

Thanks!

glad you finally got yourself a set. no change in wiring should be needed.

Not complete yet champ, still TRYING to find a RH side light

Just preparing myself...

oh. well you should be fine. there should not be any new change in wiring involved. unless your car is some special fluke lol

The bi-xenon wiring is different than the halogen one. You will need to either:

Mod the existing wiring to operate the bi-xenons & get rid of the bulb failure warning. Bi-xenons have a 3rd plug that triggers the flap when you turn on the high beams.

or

run new wires from the headlights up to the LCM. I haven't seen a bi-xenon wiring loom for sale so you will probably have to make your own. Then you will have to find out which pins on the LCM correspond to the bi- feature. After you finish with the wiring, you must take your car to the dealer to recode the LCM for bi-xenons.

The only plug and play thing are the headlight screws, low/high beam plugs and autoleveling plugs

yea, so in essence, it's the same. he doesn't need to change anything unless he wants to make the bixenon function work.

****, well yes I want to use the bixenon function... So I need a wiring harness, oh god!

That will be impossible to find or work out how to get it working. Will I need to recode the LCM to get Xenon low beam working only without warnings?

Ok, found a few DIY guides, all very complex but maybe a smart electrical guru can do it here locally.

Seems its a straight fit for a low beam xenon only. And if they flicker, ill get my LCM coded to BiXenon and do the retrofit/DIY project

If i buy a local LCM for biXenon can I just swap it over? I heard there are milage tamper issues with swapping over LCM's?
