Can anyone ID these connectors - LS2 Engine Harness
Actually, if anyone has a diagram where I could look up what each of the connectors in an LS2 (2007 TBSS) engine harness, that'd be awesome as well!
Sorry if it's hard to make out in the pictures, but any help would be awesome!
Click to enlarge pictures:
1. TCM connector?
2.
3. Injectors
4.
5.
6.
7.
8.
9.
10.
11. Foward O2 sensors.
12. Injectors
13.
14.
15. Rear o2 sensor
16. Rear o2 sensor
17.
18. Reverse light switch?
19. Automatic transmission round connector?
20.
21.
22.
23.
24.
25.
Thanks.

I am very confused. You have 3 plugs already plugged into the computer, and the blue one you have marked as #1 is supposed to plug into that. It's the other end of the pedal part of the harness. I have no idea what you have plugged in there now.
I think 14 is the one that plugs into the gas pedal.
As for the rest, I'm not really sure.

EDIT: If you don't already have it, this should be the pinouts for the 2007 TBSS E67.

I was able to find a scan from a book that showed what most of the connectors were and I matched them up with the wire colors in the wiring diagram above (Thanks Tipsy!).
However, there are these last three that I still haven't been able to figure out what they are for.

2 pin black and orange connector is for the Alternator.
2 pin grey and blue connector is for the A/C compressor
The last one is a body connector. It would have plugged in to the body wiring on the Trailblazer for communications with the dash, BCM, etc. Probably a few power wires in there also.
