Installing a new engine harness in my 70 SS 396, 4 spd. Adjacent to the oil seding wire is a black wire with a small rubber boot. Can anyone tell me what it is for. It is not on the harness I am removing

Thanks

70 Velles have the T.C.S. system. Not sure of the color "Have to look at the drawing " This wire may go to the 4 speed, The 4th gear shift arm has what looks like a " Back up light switch " For the factory TCS,
a wire plugs into this sender on your 4 Speed.
Years ago I thought it was a back-up light switch, Then my buddy said " Why a back-up light switch on fourth gear?
This may be where the wire should go??????????????

Thats another issue. Mine is close to original but missing some things. I have the original manifold but not the TCS system. I saw the TCS in the wiring diagram. Are the components still available?

I also have a Hurst shifter, I will need to look for a connection.

What does the TCS do

Thanks

Joe
