my headlights dont work they are not getting any power. the rest of my lights work. the bright light inictor wont come on either the little blue light in the gages. i switched the headlight relay with 3 diff ones and still nothing. the headlight motors work. i replaced the switch. its a 87 n/a with a pre 89 engin and harness. could it be somthing wasnt pluged in? thats all i can think of right now
