I just finished with a S5 T2 swap into my S5 GXL.

Im trying to get my cruise control to work, I found a S4 T2 servo type unit but its not working. My original NA S5 vacuum type may work but not under boost, plus the cable is too short.

Question, is there a S5 T2 servo type unit? or are they both the same?
I want to rule out if the S4 T2 servo type unit I got from the junkyard is good or bad, or if the CC computer isn't compatible with S4. The CC computers are different from S4 to S5

 

Sounds like you just need an S5 turbo unit. As is looks like you have the other options figured out.

 

That is my question.
"Question, is there a S5 T2 servo type unit?"

 

If I recall correctly there is one, electric motor driven one.
