Default Help - ODBII connection

Hey all,

I need a little help with my wiring. I have an 05 5.3 truck motor with all of the wiring. I am looking at the PIN out xls file for the C100 harness, and there are multiple lines that read like they would be my serial data line:

F orange/blk Class 2 Serial Data (10 series except HP2)
H Dark Green PCM Class 2 Serial Data
R Yellow Class 2 Serial Data (M74)

Then you look at the ODBII Standard wiring diagram that is in the FAQ and it says:

Pin 2 - Purple Serial Data Line
Pin 4 - Blk Ground
Pin 5 - Blk/White Ground
Pin 16 Orange - 12 +


So which of the C100 wires goes to PIN 2?

Thanks,

Orlando
