Indeed the tail lamps are a single bulb type (1157) and rectangular and they are each grounded to the frame. I've got very limited for electrical under the hood except the starter selinoid, voltage regulator and the ballast resistor (a leftover from the points ignition system I left in place for a period look). The car has no blower / defroster, windshield wiper motor or related hardware (Hey it's California). The only other electrical under the hood is the wiring harness to the headlamps, alternator and fan.

The Contemporary Assembly Manual makes no reference to such a relay box. It identifies the wiring harness as a "late model GM" which means it might be circa 1980-1985. It does identify the directional light controller as a Volkswagon unit and it seems to be operating properly, the relay housings are clear and the relays operate as they should. This suggests the switch is not the issue and confirms my guess about the turn signal stalk / switch being vee dub.

I'd like to thank all who chime in, I'd hoped someone who'd had the same problem might drop by with a easy fix. I know you are all busy supporting your families as well as your addiction as I am, but I'd particularly like to thank strictlypersonl who has a personal interest in many hundreds of Cobras as well as a life. Thanks to all.

I'll be running down the potential faults as time allows. It's been over 105 degrees all week and the sun hits the new garage until about 8:30 here. As much as I'd love to bust out and test everything that might be wrong getting quality garage time has been tough. I'll update you as I know more. I will be out getting another flasher unit tonight and will put it in tomarrow, and run down a few other leads tomarrow.

Thanks again.
