Is there anything on the other side of the firewall around that location? what if I drill a hole a inch or so somewhere around that location and retain the clip for that wire loom will I drill into something on the other side?
Yep or the fuse block under the dash, in the floorboard, left side.Just run wires to the fusebox on the left side of the dash. That is how I wired the CB in both my '99 and '07.
