Wire Loom on 37 Buick

Hi, I need to get the brake lights working on a 37 Buick four door. Got juice to the brake switch and also coming out. Nothing to the lights though. Looking in the trunk and the wire loom looks to go back to the inside of the car. Is it going above the headliner? Back down under the sill plates? Any help would be appreciated. Thanks Jon

 

Thanks for the come back. Followed the loom and found nothing wrong. Went back and doulbe checked the switch. Sure nough, the ****er was bad. Got a new one and got brake lights now. Thanks again. Jon

 

Glad you got em working, just an FYI the wiring does run up inside the headliner over the drivers side doors. Hope your wiring insulation is better than mine was, my original stuff was all crumbling and was an eletrical fire waiting to happen. I tore it all out and went with a newer harness.
