Well for my 99 it was the White wire going into the ECU.
I guess you have the 4wire o2 sensors? 2 Blk 1 wht, and
1 Blu?

For the correct wire goto your Local Dealer and have them pull
up your ECU wiring diagram they can and you will be sure which
one and which pin.....Hope that helped

i figured it out by shoving my digital multimeter in the white wire that went into ECU and started engine...the numbers began counting up and started fluctuating from .1->1v so that was it =]

thanks for your time!

If you do not already have it sorted, email me and ask me for the diagram you need and let me know what year truck, model and tranny you have.
