I have done this mod on my 2500HD and love it. dont have to push the fog light button every time and all 6 lights stay on when i hit my brights. i just picked up the 07 MCSS and was looking around and i dont see the relays that i can put diodes on like i have on my 06 2500HD. any one on here ever done this mod and if so how did you do it? my biggest thing is just making it to where the fog lights come on with the low beams without having to hit the button every time. thanks for your help.

I have done this on many cars. I just wired the fog light power wire to the headlight power wire in the passenger compartment fuse box panel.

I thought about doing this, but I like running with my park lamps and fog lamps on without headlamps, so thats not an option for me anymore.

This is what i did on my 2500HD and was hoping to be able to do to the MCSS...just dont know where the relays are for the hi/lo/fogs

Owners manual should tell you which relays are for what. Or you can look on the underside of the fuse box cover, that might tell you also.

Looked in the owners manual and on the covers of all of the fuse panels i could find and never found the 3 relays. is there another hidden fuse block somewhere? trunk maybe? found the one on the passenger side and the one under the hood.
