    Somewhere on Moates' website is the setting to get the Autprom data out of your datastream.

    or is the 4 jacks on autoprom more input channels... so the red doesnt get power from autoprom...and the black still goes to chassis ground...? that leaves the blue and white going to autoprom as input signals for the datastream?

    You'll have to read the directions for your wideband. As for the AutoProm there are 4 wire conections, closest to USB cable is ground and other thre a re three input channels.

    ya know ive seen that video befor...
    looking at wideband instructions....
    red 12v power
    black ground
    white 0-5v output
    blue serial output

    so the blue is not going to be used?
    hook up the white to autoprom and run a ground
    easy enough!....my confusion was brought on by having 4 wires and spots for 4 wires on autoprom. thought they all needed to connect to autoprom...lol...problem solved!
