    Hello

    I have a 1995 k1500 ext cab. 5.7l 4x4.

    It is missing the purple o2 sensor wire. I've chased two purple wires from the fire wall but they appear to go to the fuse box.

    Can someone tell me what wire it is at the firewall so I can run my own wire and not cut the wrong wire.

    Thanks.
