The connectors on my '70 Z (5/70) are large. When I order a harness, I get ones with small connectors. What is he correct size? The connector from the harness has the larger connector. See pics.

Large connectors were used on Series 1 cars in the USA, through about 12/70 production. The small connectors were used from then through the end of '73 production. The early style (large connector) taillight wiring is different from the later cars, too. In the early cars both upper bulbs work as brake lights, but only the outers are brake lights in the later cars.

I may still have a pair of the correct large connector taillight harnesses. PM me if you're interested.

Is there a source for the bulb sockets? Both my Backup Lamp sockets are badly corroded and need replacing. Thanks.

Thanks, Arne. I contacted ZSource, they had sent the wrong harnesses. They sent the right ones and gave me a shipping label to send the others back.

BTW, pardon the dumb question: With the key off, if I step on the brake pedal, shouldn't the brake lights come on?
