Re: Heated O2 Sensor Installation
I hooked the other side of the connector to the 02sensor power and ground.
I clipped the old 02 the signal wire connecter off and put it on the new heated 02 signal wire so that can be hooked back into the factory harness just like stock.
I hope that makes sense..

Re: Heated O2 Sensor Installation
Same here. You can grab the power from the fuel pump relay feed wire, and stick the ground wire on one of the screws that holds the relay bracket to the firewall. It's close to where the stock O2 wire ties into the harness, so you can run them all together and stick some loom on it to make it completely disappear.

Re: Heated O2 Sensor Installation
I'm about to do this install tomorrow and am having a tough time finding the right wire to tap into. In other threads I read about a pink/black wire, but in my wire loom there are 3 different pink/black wires and the only end I can find goes into the EST module. Any suggestions?

Re: Heated O2 Sensor Installation
the switched side of the pump relay which in the typical F-body pump wiring diagram shown below would be the
tan / white wire out of the pump relay connector (running to the pump )
Could also connect to switched side of the pump oil pressure switch , same difference

Re: Heated O2 Sensor Installation
Ended up doing as TTOP 350 did and ran the power wire straight into an empty IGN slot in the fuse box. Thanks for the help anyway, vetteoz.
