The brake out of the pedal switch goes to the turn switch to send the signal to left, right or both depending on turn switch direction. Is this an aftermarket harness...different that stock?

Attached is a generic drawing of how a late '50s and early '60s GM turn signal switch works. Wiring colors are correct for my '57 GMC. Ignore the colors for anything else. The top drawing is with the turn signals off. The center is signaling a right turn. The bottom is signaling a left turn.

Ferris: I had a constant draw through my steering column when I first hooked it up a couple weeks ago and the left brake light never came on.
I sprayed electical contact cleaner in the switch contacts and just worked the turn signal stalk back and forth for a couple minutes and it cleaned up.
You might try the same. It is a cheap/easy fix if it works.
Currently the guts of my blinker assembly is sitting on my work bench cause I couldn't figure it out a few months ago. This is in conjunction with a gap I have between the wheel and the collar I can't get rid of, a top bearing that won't stay in place, etc.
I might have not cut the shaft short enough when I was installing the new steering box, but who knows at this point. I guess this weekend I will rip the wheel off and try to figure out what is happening in there.
