Hi Ron, I have been looking up an issue I have with my CPS (saab 93 1999 auto 2L) and notice you responding quite a lot. I am hoping you could shed some light. My mechanic tells me i need a new cps, and he has had delivery of 2, but in both cases they were a 3 pin connector, but that the one in my car has 4 pins. Im trying to source one, but all i see is 3 pin connectors, and have asked him to make sure. He has got a bit irrate with me, saying its 4 pin. Is this possible?
