don't go by wire colors...if you get one of the power and ground backwards=bye-bye sensor.

get a multi-meter and check continuity for ground by touching the middle pin of the stock 3 wire harnes and the neg terminal (you'll discover that one is ground)...there saved you a 3 bar.

next, to determine which is 5v and which is reference (less than 5v) take you meter and switch it to dc and probe the middle pin and one of the other 2 left. the one you see 5v is the power and the other (should be less than 5v) will be reference.

assuming you have a gm or a msd 3 bar the plug configuration should be as follows and is labeled on the sensor and/or plug:

a=grd
b=ref (less than 5v with your meter)
c=5v

splice/solder the 3bar connector into the stock wiring just in case you have to switch back to the stock sensor for any reason. keep the stock sensor in the tb to plug the hole and keep it disconnected from the harness plug.
