Need to hack into the headlamp wiring to set up my fogs as DRLs. There are warnings everywhere about the 25000 volts on the bi-xenons so want to make sure I get this right!

I need to pick up an ignition feed (to turn on the DRLs) and a "switched on" feed (to turn the DRLs off when the headlights come on)

But what about the 25000 volts  .

The description of the wiring and feeds for halogen and bi-xenon appears to be the same, but i don't know enough about it to say yeah or nay. Suggest start a new thread for this?  .

Joe, the high voltage is within your headlamp pal... The feeds to the plugs are all standard 12v, the ECU's and High voltage box is hidden inside the rear of your headlamp...

And yes the wiring colours you mentioned are the ones you want...

Really?

My tdv8 has xenons and I thought they all did

Are you talking about the separate high beams? If so, I believe it is normal for these to be halogen still - something to do with the fact that xenon doesn't come on instantaneously, important for flashing the lights - the main beam shifts it's pattern to be full beam slightly later

In all L322's from 02-08 you can get both Xenon and Halogen headlamps depending on spec... Only the 09my> that comes with Xenon headlamps across the range...

tim,

the high voltage only occurs from the ballast to the hid bulb, the ballast is fed by 12 volts which ends at the end of the plug .... ... - .- -.

Thanks for your guidance  .

Is there an "easy" way to put the headlight unit back in. Seems you have to fiddle and struggle for 15 minutes, then suddenly it slots into place  .
