I have a 04 colorado with signal light drls. So tonight I did the dual high beam low beam mod.....everything worked fine. Then I did the fog lights that stay on with high beams mod (for signal light drl) .....it works just fine too, except that the illumination does not come on for the headlight control panel.

I don't recall that it will because the BCM doesn't know the fog lights are on. The modification is done "downstream" of the BCM.

I done the dual head light mod... I later added fog lights and tied into the license plate light harness... That way the fogs are on if lights are on... No matter bright... Or dims !!! Good luck finding the gremlin....
