    This is specific to the 5.2 Motronic 355's (1996 to 1999). There are two Amp connector plugs that go to the solenoid (vacuum) valves on the right rear of the car, behind the bumper. One is black, the other is blue. When you look up under the bumper, the blue one will be closest, and the black one will be more to the left side. I need someone to pull the black plug, peel back the rubber boot, and you will see a green/black wire and a blue/yellow wire. Note the plastic connector housing will have a "1" and a "2". Just need to know which goes to 1 and 2.

    I am marking all the wire colors and locations on the Amp connector plugs on the 5.2, and in a bone headed move, took that one apart before noting the locations of the wires.

    Thanks in advance friends! :)

    I have mine partially disassembled right now since I am chasing down a vacuum issue. I will take a look in the morning and get back with you if someone hasn't already answered by then.

    Thanks Tom,
    That would be great. Dave Helms checked his wiring diagrams and it appears to not matter the polarity, but it would be nice to have this information regardless.

    Standing by...
