Question Rewiring Fog Lights to Work with High Beams

Does anyone have a wiring 'how-to' for making the fog lights independent of the high beams? Basically, I sometimes want them both on, but turning on the high beams disables the fogs. Thanks!

Actually it's a bit harder than that since it's all handled by the "front ecu" that's in the PDC.

Under the hood there is a relay to control the fogs. This relay is after the ECU that controls the fogs/parking lights/headlights.

Basically you need to add another relay to let you switch between your override and the standard relay.

It's all in the service manual, although it was kind of a beotch to figure out how to read the wiring diagrams.

I think it's possible to sidestep the ECU, I just have not had the time to check it out.
