Well, continuing to chase electrical gremlins on this truck. The first time I tried the headlights after I did the tbi conversion they came on for a second and then died. I now have no headlights or parking lights or tail lights but turn signals and brake lights work.

Took the switch out and there is no power to it. The wire that comes in from the jct block on the firewall has power through the fusible link and all the way to the bulkhead. It seems to go dead somewhere under the dash but it is my understanding that the wire goes directly to the headlight switch once it comes through the firewall...

Any ideas? I'd trace the wire from the firewall to the switch but there is really no room under the dash to do anything...

Thanks.
