I have just installed a new 7 wire turn signal switch from American Classic. I ran new wires for tail lights and turn signals. Also installed new 2 bulb tail lights and new grounds. Everything works except the brake lights. When I pull out the brake light switch on the flasher the rear flashers flash. With the switch off the brake lights don't work when you depress the brake petal. I also rewired the brake switch.
Does anyone have an idea what I should try next?
