    dark blue is the signal wire. Connects to the black wire on the sensor

    The other two are ground and heater power. Those go to the white wires. Doesn't matter which goes where. I think the orange is the ground but not 100% on that. Don't have the manual in front of me.

    Cool, thanks!
    It looks like the orange may have been unused?
    It was inside the loom a couple inches from the end (couldn't see it till I untaped & split loom. Odd part was it was stripped to like 2 inches of bare wire.

    The orange wire should land on the back of the block, and it also goes down to each O2 sensor. heater won't work unless its got power and ground.

    the orange one with the big eye is the sensor ground that goes to the block. I was thinking that was also shared with the O2 sensor ground circuit.
