FAQ

How will the lights function after I install this?

Any time the park lamps come on your fog lights will come on. This means if you leave your switch in "auto" mode, the fog lights will always be on at night.

How long does installation take?

About 5 minutes following our video!

Help! I installed it and it's not working properly.

Please verify that you installed it based on the pin locations, NOT the wire colors. GM sometimes changes wire colors however the pin locations always remain the same.

Please contact us if you have verified you connected to the proper pin locations and are still having issues.
