DIY: of complete FOG LAMP install

Hi yubman!

I hope I understand you correctly…
It is necessary (no choice) to splice into the green cable (for braking) but I wouldn’t slice the black cable of the light assembly for the ground… Just ground it to the chassis directly and not into the tail light. As I mentioned above when you open the inside panel (It’s needed to remove the tail light assembly) you will find a nice ground bolt there (it has many other ground connection to it) and you should use this one. But since it’s inside the truck, you will have to go thought a rubber grommet. Otherwise, there are so many other ways to find a ground… (Licence plate, tail light, direct chassis) My choice of not using the tail light ground is that I didn’t feel comfortable completely using the LED circuit because the fog light uses a regular bulb that draws more current. Besides, I also had wire a special flashing module so it was better for me to do all this from inside the trunk.

As for the InvisiCord setup. Maybe it could work… but it’s really no big deal to tap into the OEM cables. There are even some clamps especially for that (you can find them anywhere) and they won’t even cut your original cable in two… it will just make an opening to access the metal wires and create a bridge for your connection... Takes about 2 sec.

Also do you think it would be possible to use a InvisiCord (Invisicord Products Home Page) or something similar to tap into the OEM socket rather than slice the wires? I'd rather not cut/splice the wiring harness if nesseary.

Thanks for the great info, once the snow clears and it gets a bit warmer I'm hopeing to get this done along with the lighted sill plates.
