Default 04 LQ9 Harness Help!!!

Alright, I bought a harness off of ebay from an 04 LQ9. The seller states all was well and in working order. I received it and found that a bundle of wires has been cut. They are 19 wires that come off the harness right before the injector bank that also has a 7 pin gray connector and a black/purple connector. I've been looking for harness pictures and could only find ones of LS1 harnesses with a t56 from those the closest I could figure was that it was for the trans, but then again there is a large circular 90 degree connector that i think also could be for the trans that's still on the harness. I looked at the pinout diagram and it didn't clear much up as i have wire colors that don't match the diagram for alot of the 19 wires.

Can anybody help me out?

Thanks!

Post good clear pictures of your harness. We can tell a lot by looking at it.

Here are the pictures. The bundle of wires that were cut are located in the lower left hand corner of the full harness picture. The upper left hand corner was cut off in the picture but the power junction block is up there. I appreciate your help.

It looks like the part of the harness that goes down around the front of the motor and catches the AC compressor, the crank sensor and oil level sensor, it might also have a heavy purple wire that catches the starter, if its cut off short enough, even one of the O2 sensor plugs is missing

if this is the harness you bought from me, i stated in the description that some of the wires had been cut, and i included pictures of each and every section that had cut wires.

if this was mine (im trying to go off memory, i took the harness off a long time ago) the 19 wires i believe went to the front of the motor, probably for a/c and whatnot.

Looks like the wires running to the C100, or whatever it is, connector. The wires that used to run to the interior of the truck.

Nope, didn't but it from you. The auction listing had no pictures, I caught it at the last minute and the seller had good feedback so I bought it. So far he's been really great to deal with, I just need to figure out what's missing so I can determine how to fix the harness.

The seller is supposed to send me the vin tonight of the truck it was off. Maybe then I can figure out if it was 2WD or AWD. The truck was an 04 Silverado SS.

Make a list of the connectors you DO have and compare it to whats needed

Should be easy to determine then

I just fixed the link should work now. http://s237.photobucket.com/albums/f...ing%20Harness/

I posted the picture of what he is missing as well. The first 4 is what he is missing in his harness. The other ones in there are what im trying to figure out what they are and if i need them or not.

Its an entire section that branches off of where that cut is. Some did not turn out all too well.

I will post the ones he is missing here too, hope they are not to big.

The first one looks like an O2 sensor and the last one looks like the 5 wire maf plug
