BOTH blink very brightly (and it doesn't matter which way i turn the switch, they both blink if the headlight switch is pulled one click) also, the brake lights come on, but are also very dim.Indy
I think your problems that the tail light wire is going to the turn signals. You have three wires coming off the firewall and routed back to another connector by the spare tire. The wired harness for the rear lights mate to that connector. IIRC the black wire is the tail lights and goes to both sides. The other two wires split one to each side. These wires are are both brake and turn signals. Forgot you have a fourth wire, backup lights. Also check your sockets to make they haven't been molested.
