It works by grounding the fuel pump relay. The circuit is part of the 78 wiring diagram in the factory manual. They call it a speed switch. It cannot be adjusted that I know of. It can be disabled, by disconnecting the brown/red wire. I think all cars are the same on this.

Chris,

You are correct about this rev limiter for SC's. However, if your go back to you earlier post (wiring diagram) the red/white wire should be connected to the tach instead. Not speedometer!!!! I don't see how a speedometer could stop an over-rev engine during a test!!!!. Any thought about this? Thanks.
