Thread: Need Connector pinout for 1994 Silverado/Sierra

  1. #1

    Need Connector pinout for 1994 Silverado/Sierra

    I need the pinout for the black connector under the glovebox that's right next to the PCM connectors. The 1993 connector is completely different. The connector joins the engine harness to the dash harness and has the Serial/Class 2 lines, VSS lines, and TCC lines. There are several other wires in there (like 3 or 4 white ones among others) that I have no idea what they go to.

    FWIW, the 93 connector was called C200 IIRC, maybe this is the same name for the 1994 connector?

    It's 2 rows, black with blue secondary locks maybe 16-20ish pins?

    Not handy, should have taken one. IF you remember what the PCM connectors look like on the TBI controllers, it's the same type, just wider. Black, t-row, blue secondayr locks. About 16-20 pins, not all of them used. I am pretty sure it's called the C200 connector even in 1994. It has the VSS, TCC switch, class 2 wires etc.. on it.

    I have one in paper form for a 91. If it's the same I can either scan it or dig up the digital version.
