PCM pin assignments?
I have found them for the 98-02 F-body's on ls2.com but no info for our trucks. Anyone have this information? Especially for 2005?

Particularly the bank2 sensor 1 wires. I have a problem with bank 2 being consistantly more rich and reading richer. Also I have burnt up 3 sensors in that location. It is 3 times as slow to warm up and start switching than the bank 1 sensor even after I swap them. Figure I have a resistance problem somewhere.

Hey MJ,
In the blue connector, pin 26 is th elow signal
pin 66 is the high signal
pin 74 in the green connector is light green, and is the heater circuit for bank 2 sensor 1

English por favor. I'm unfamiliar with the high and low references.

just glancing at grumpy's post I didn't see what year he was referencing (his vehicle year isn't in his sig). I have a 2000. My heater and 02 signal grounds are (were) case grounded. The 2002 isn't. Just consider my posts in this thread useless as I KEEP forgetting you are an 05 and I am sure grumpy hooked you up with the right pins because he says..."In the blue connector, pin 26 is the low signal". Not case grounded.
Carry on. LOL
