    I have an '09 GMC 2500HD and i am installing an older Western Uni-Mount 8.5' MVP v-plow. I have the snow plow prep package and i can't seem to find a good place on the firewall to run the wiring harness into the cab. I don't see any visible or obvious grommets. Anyone know something that i don't that could help?

    I just pushed in the large grommet right behind the fuse block on the left side of the drivers side. Worked out good. I had to run strobes,salter control wire and western plow cab control wire.
