Starting around March 78, alarm switches were incorporated into both the left and right, rear t-top receivers. From then on, all 78-82 Corvettes had the t-tops tied into the alarm system.

Hmmm, that is a new one. Guess they skipped mine. Do the wires run up the side and is this switch something you can order, never seen one before.

It started @ vin 25281 (regular production) and vin 04658 (limited edition) and all 79's.

You can test it by setting the alarm. (windows down) and then try to unlatch the t-tops. Alarm should sound.

It ties the t-tops to the factory alarm system.
