    Unknown wire at D13 on C1 ECM plug

    Can anyone tell me: The C1 ECM (larger plug) on my 87 GN has an unknown wire in it at the D13 position. According to the schematic I have this position is supposed to be empty. It is definitely not factory installed and is not run with the regular harness and it is not hooked up to anything...
