tail lights

[427 S/O]

I've wired the car and everything works,
it must be charging because it starts everytime.
Problem....I have the single 427 style tail lights each with one double filament bulb, I have brake and turn but no running lights, how do I wire to have all three?.

Normally, the parking lights are on the dimmer filament and the brake and signal lights share the other filament. To do that, you need a relay. The cheapest way is to use a trailer relay that converts a 3 filament system (like most GMs) to a 2-filament trailer. They're available at most auto parts places and trailer dealers.

Thanks Bob, I noticed on my CJ7 that the
break light is replaced by the turn signal.
