when i put mine in, i just spliced the wire that was in the engine bay, coming directly outta the O2 sensor....then ran that in through the little hole for the throttle cable, up to the pod.

I did the same exact thing. I wonder if there would be a different reading from that location and the ECU? .....probably not, just curious.

I'm using an Autometer Phantom series....

if you dont have the book, you can use continuity checker. put one end on the o2 sensor and start checking pins, i would recommend you still use it to double check
