Re: Relays
I'm guessing horn relay.

Re: Relays
Most likely the horn relay and TCS (if it's a later year - I think TCS was only 71 and 72).

Re: Relays
I was thinking horn relay too but it looks like I have one already under the dash. Should be fun to figure out. Gotta love wiring.

Re: Relays
Looks to be a Transmission Controlled Spark Solenoid. It is designed to not allow vacuum advance until you are in a higher gear and the engine is up to temp. A very primitive emission control device.
Found some info here: https://www.ebay.com/p/NOS-GM-1971-C...0843/658409486 Here: https://www.autozone.com/repairguide...00c152800515a5 And Here: https://www.corvetteforum.com/forums...-solenoid.html |
