I don't know off the top of my head what if connects to but it's a unique connector so it should be very easy to figure out. Perhaps this photo will help. Image Unavailable, Please Login
That is only on a 95 355. There are two of them left and right. The wiring diagram calls them Rear Engine Connector. It is how the main wiring harness gets to some of the other components in the wheel wells and rear bumper like bypass valve solenoid etc... The wiring diagram has the pin out. Or I have them. My guess is they are Bosch xx pin connector. I don't think you are asking to buy them, just what they are.
