Several makes and styles of aftermarket turn signal switches were available back in the day. Some connected the turn signals, brake lights and parking lights with as many as 8 wires. How many wires are coming from the switch? What make/brand is it?

There is an old tech tip from Cletus about trouble shooting aftermarket turn signal switches, etc. Maybe it will be useful.
