    What is this plug?

    I recently swapped from motronic 1.0 to 1.3 and got the car running. This is still unplugged, what does it go to?

    Right now it is just dangling in my glove compartment and my obc seems to work with it still unplugged. Picture taken from strictlyeta.net.

    No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.

            Pretty sure they're C131 and C136.
            C131 is used if you have an automatic transmission, not used for manual.
            C136 is tied to the AC circuit.
            Both feed the the ECU to change idle speed appropriately.

              Thanks that sounds right.

              'C131 is the Park/Neutral signal to the ECU pin 42 - engine should not start if this is bad or not connected
              and C136 is for the A/C as BMW BUM suggested - it tells the ECU to run the engine differently when the condenser is on.'
