Which wires are power and ground for the ecm?
Looking at my wiring info, it looks like there is 1 orange wire that needs constant, there are 3 ground wires behind the drivers head.
Are there more I'm missing? Just looking to get the computer to communicate with a diagnostic reader
thanks!

I don't have the wiring info in front of me, but I recall wiring:
Constant: ORN C101 G - 10A
Ignition to:
C100 A -page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } --> (IGN/INJ Bank 1 15A)
C101 B - (IGN/INJ Bank 2 15A)
C100 G - (Tranny/EGR 15A) - I rewired this to my Reverse lockout for T56
C101 E -PNK/BLK 15A - PCM 19 Ignition Positive Voltage for PCM
C105 B - &nbs

well i pulled the computer and grounded all and had power to both places, but still no communication
starting to look like a bad computer to me unless i'm missing something...think i'm going to focus on getting everything else done and see what happens when i turn the key...if nothing else at least the rest of the car will be done

I'm going to double check again, but I believe the wire was purple, 2 grounds, and a hot wire to the port.
And correct, when I plug in the Snap On scanner and go to anything it says "waiting" and then "no communication"
Someone told me it could be locked by a handheld tuner, is this true?
