I have searched to no avail. Has anyone figured out how to jump foglights to come on whenever you turn on any outside lighting?? I know in my gmc you can add a diode jumper from driving light relay to fog light relay. Would like to be able to do the same here. So for all you electrical engineers out there here is the link for the GM mod.

I know my fogs would turn off with the high beams on, so using NCSExpert, I was able to enable them to remain on when high beam engages. I was sitting the other day in the parking lot with my running lights on, and wondered if my fogs would engage with the flip of the switch and they did! I don't think I was able to do this before.

 

That's standard operation (see the Owner's Manual).

 

This module can turn on the fogs automatically with the headlights: http://www.fes-auto.com/products_det...p?productid=35
