Also trying to find a schematic for that part of the truck, is proving quite difficult. So far I haven't found one.
I had noticed that particular schematic didn’t exist either. I do know that on my 94 there’s 7 wires that control the lights from the inside passing through the firewall. There’s plenty more wires going through the same place, but only those few I mentioned on mine are the items of concern.
What year is yours again @n8pu ?
