Fishing wires for 3rd brake light. Can’t seem to make it work.

[Gander]

Any advice on how to get this done? I’ve got a factory cargo light, and I bought the United Pacific LED replacement for its bulb/lens. This thing also had red LEDs in it that work as a 3rd brake light. I know where to wire it up at the brake switch, or at least I think I know hahahaha! What I can’t figure out is how to fish the wires down to the floor to run under the door sill plate and up to the brake light switch. I took the cargo light off and also the cargo light switch out and tried to push some baling wire through but just couldn’t get it. Any tips on how I can get this to work?

Can you use the existing wires to the cargo light to pull a fish tape down and return the wires the same way?

Can they be taped to the interior cab roof, hidden by the head liner, and windshield pillar? That’s my plan B if I have the same issue as you do fishing the wires in the roof space.

I went from the hole where the light is and fished it towards the drivers side corner - it drops down where the behind the seat speakers go. Pretty straight forward and took me (maybe) 2 tries?

OK, I’ll take the drivers side rear speaker bracket out and try again.

You could try an electrician's snake. They are stiffer than bailing wire.
