    OBDII wiring question

    I have a 98 5.7 LS1 that I got from a Junk Yard, Unfortunately it did not have the OBDII connector on it. I bought a replacement but it did not come with any instructions on tying it in. Where does it tie in to? Anyone have a 98 diagram?

    If the wires are just cut here's what my helms says about the colors, not sure but think '98 is the same.

    Pin 2 - PPL Class 2 Serial Data
    Pin 4 - BLK Ground
    Pin 5 - BLK/WHT Ground
    Pin 16 - ORN Battery Positive Voltage

    Thanks man. I dont remember seeing any cut wires. I guess they could have been cut and then tucked inside the plastic shielding. I was also wondering if someone could tell me what the round green connector is. The one that is about the size of a golf ball.
