2004 Pontiac Grand Prix, keysense

Trying to find the key sense wire for an 04 grand prix. Directed and astrochart say pin 40 Green wire under the dash, I found that pin and tested it with a multimeter, with no change from when the key is out and in and turned in the ignition.

Any one have any hints?

Yep, I see there are 2 wires on one each side of the white wire, one tests 0 volts with out the key in, and tests 3 volts at the ignition position. The other one (the one at pin 40) tests 0 at key out and 0 at key in and 0 at key to ignition position.
