That's the 4-pin Clutch Anticipation Switch, 99-02 LS1 F-body. Two are for cruise, other two go to PCM..if I remember right.

That pic with the two connectors is how I did it.

 

thanks merv. so on the anticipate switch i can use the 2 wires for the cruise control and do the other 2 need to go to the pcm for the car to run? to my knowledge it just lets the pcm know when you push the clutch in so it can "flare" the rpms a bit so i would think not?

 

Ya that is what it is for..find a pinout for that switch so you know what wires go where.

 

ok thanks merv I'm currently looking for a pinout but i should be able to just hookup the cruise wires from that in series with the ones on the brake switch and leave the pcm anticipate part out and it should be good right?

 

Yup..
