im in the process of installing my gm maf and i need to know wich group is wich off of the ecu+ hu. the manual is a little confusing when it comes to marking groups so if someone could tell me wich one is a, b, c, and d that would be great. picutures would also help me out a ton.

 

dude the pics are in the manual

 

left to right ABCD in that order.......the farthest left is A

 

The 'D' group is the one with only 4 wires (brown one tied off). A,B,C,D, and the wires are grouped together with tie wraps near the black connector.
