if this should go somewhere else im sorry. im looking for colored wiring diagrams for a 2001 silverado 1500 with a 6.0l and 4l80e. im swapping the whole setup into my 66 and want to keep the whole harness from the 01 the way it is. i mainly need to know the wire colors for the passenger side front 02 sensor. also i need to know the colors of the tail light and head light/blinker wiring and where it exits the harness at. there are also a few other connectors cut off like the gauge cluster connector (i think thats what the wires are) and several other connectors that would go under the dash somewhere. since there are several wires there that are the same color i am going to have to trace those back to the ecm/bcm or wherever they come from to find out what they went to. something that would be very helpful is a plug identification chart if something like that exists. something that would identify plug color and type and list what they plugged to, and list the pinouts for each plug. i have ecm and bcm pinouts but have had no luck with colored diagrams. i used mitchell on demand from work to get the pinouts. i have heard alldata has better diagrams. is this true? any help anybody can provide is highly appreciated. if you need pictures i can take them tomorrow.
thanks,
John

and heres what i think they go to...

red = i think these go to the doors for the power windows/locks and such
yellow = i think the yellow one went to the air bag, and the big black connector went to the column for the ignition switch, wiper controls, blinker switch, and cruise control switch
blue = the PO cut these when he pulled the harness, i think they went to the gauge cluster/info center
pink = i have no idea what these two connectors went to. they were inside the firewall. any ideas on what they went to?
black = these go to the under hood fuse box as i unhooked them myself.....lol
green = these split off from the harness right before it enters the firewall. it looks like they headed towards the passenger side. maybe the blower motor? something to do with the ac? i dont know.
orange = i know this goes to something that is close to the headlight switch but im not sure what as i dont have access to another truck i can reference to.

you still need, if so email me at rockfan1815@yahoo.com The diagrams can't be posted or sent over the board.

I've got the full manual set for 2003, so I can probably get you the info you need. private me if you'd like me to check.
