The Stovebolt Site Forums The Shop Area The Electrical Bay No brake lights

I wired in LED tail lights as my nut-and-bolt nears completion. The running lights work but not the brake lights. I checked and there's no power to either of the leads at the switch up front (with the key on).

Just so this truck can be road-worthy is there some reason I can't run power from anywhere - the battery - to one side of that brake switch? Yes, it would be a constant power, but it's not like I'll sit there with my foot on the brake pedal overnight.

If that works, does anyone know off hand which color lead is the incoming?
And where I should start to do a true diagnostic?

The power feed for the brake lights will be an orange wire. Without the accessory fuse block, it should go to the headlamp switch, terminal S. That terminal should be hot all the time. With the fuse block, it would go to the Stop Lamp terminal, I would have to check the accessory wiring diagram to be sure if that is constant power or not, but I don't think it is.
Running constant hot to the brake light switch will not be a problem, most modern vehicles are wired that way. Only time it'll be a problem is if the switch fails in the "on" position.

I added a fuse block that's a constant hot from the headlight switch so I think I'll just go there. I have an aftermarket switch, so that may be where the problem lies.
Thanks!
