extra coolant temp sensor
 

I am finishing up putting the k5 drivetrain back in and was wondering what the other coolant temp sensor is for. I think it was in the pass side head and it wasent the same style as the gauge sender. I was thinking some sort of switch for the fast idle sol. for on cold morning when the coolant temp is not up but the choak is allready off?:help:

TCS...early emissions crap. Wouldn't let the timing advance onless the engine was warmed up, and you were in 3rd gear.
Kinda barbaric in reality.
