i think on the unused harness designed for the optional oem fog option

 

The way I have it wired, the fog lights:

turn on with parking lights
stay on with lo beams
stay on with hi beams
and you can use the supplied switch to turn them ON/OFF anytime

 

nice diy!

 

read my post here so you don't have to wire anything thru the firewall:

^good write up also...I've only done wiring once before this, so it was easier to run the black wire thru firewall, since there was a hole there already. Also, I didn't want to be cutting any factory wiring, because all my mods are not meant to be permanent until the car is paid off.

 

i didn't cut any factory wiring.. since the fogs didn't come with the right connectors, i only tapped into them.

as far as the crappy universal harness? yea.. i cut that apart.

 

just tap the white wire into the pink wire with the silver stripe next to the drivier light and its easy to find in the panel behind the mirror control tap that and find power and ground for the switch no need to go through the firewall and the wire is too short anyhow

 

thx for info
