taillight harness on 1950 F1-Help
 

Got a new harness to wire my taillights on a 1950 F1 Pickup. I already put the complete harness on the engine to dash. I have power on the green wire coming from light switch to the taillight at the firewall. Then I have power to the brake light switch but NO Power at the rear harness where it plugs into the taillights. What am I doing wrong???? Otherwise Power at the front of the harness but no power at the rear.

Do you have power to the Brake SW? Tested SW with VOM?
Could you have picked up, the wrong leads on the light SW?
I had to take my original headlight switch apart to clean the contacts.

I had a like problem and found that the bullet connectors were not pushed in far enough.

Are you just working with just the Brake Light? As I'm sure you know, there are two wires, Tail Light and Brake Light. The Tail Light is Black and Brake Light is Green wire. If you have power to the brake switch, is the switch itself bad? You could bypass the switch and jumper the wire to see if the rest of the harness is ok.
