Temperature sender unit

[hornet7288]

I am nearing the end of my 7mgte build and I noticed that the probe on top of the water neck directly behind the thermostat (close to the CPS) has been broken off. I am assuming this is some type of sender unit for the computer or gauge. Does anyone know if this unit is the same plug for turbo and nonturbo? Thanks!

Are you referring to the CSI switch pictured here?

 

[hornet7288]

yep that's the one. Is that one the same from n/a to turbo?

Yeah its the same from NA to turbo, but pre 89 and post 89 have different connectors.

Alright sweet. I may need another one, but I am not sure. My car is an 89, but I am not sure if it's an early or late 89. Regardless my new engine is all 89+ stuff. I suppose I could see if anyone has that CIS for sale so I could snag one just to be safe.

if you have a gray plug ECU it will have the later style connectors. The one in the pic above is an 89+, the pre 89 connectors are rectangular and use a metal wire clip to hold it on.
