I'm wiring my original 6v system on 1950 Chevy 3100 with reproduction taillights and doing toggle switch turn signals.

The problem I'm running into is, the housing has 2 single filament bulbs so I need to run the turn signals and brake through the same wire..

This site is the only one I've found that seems to have a solution, it's suppose to have the turn signal override the brake.

I got the adapter piece but it doesn't work.
Bypassing the adapter, the brakes and turn signals work independently when hooked up to the lights. With the adapter hooked up though neither the brakes or turn signals work. So it is definitely something with the adapter and my money's on I just received a defective one or its a 12v adapter or something but couldn't find out if voltage mattered with adapter anywhere.
