01 chevy Suburban power window wiring

I'm trying to install window roll up modules on a 2001 suburban. I tested all the wires at the drivers door switch and now I'm confused. Only the drivers window rests at negative, the wires are then positive when the switch is triggered. The other 3 doors rest at positive, and the wires are then negative when the switch is triggered. The modules I have are for reversal rest at ground. All the diagrams I have say that a suburban should be reversal rest at ground. Somebody help me, explain whats going on.

you have to test and right down what possitive signal wire controls what and what window each window has 2 wires when one wire shows 12 volts the other shows neg. what your looking is for the pos 12 volts so do this .. if you have a dmm take the neg lead and ground it with a clip or something take the possitive lead and check each wire make sure it shows 12 volts. then you know the ground and all is good\ then take a peice of paper and right down the following. drivers door up pos down pos drivers rear up pos down pos pass front up pos down pos pass rear up pos down pos than fillin the blanks the way it works is this take the drivers door and find the up possition possitive wire write it down than find the drivers door down possition possitive wire now when you are moving window up wire ? will show possitive and naturally the down wire will rest at ground and vise versa for goin in the down possition. just right down all the wire colors or mark them. or you may have to go into each door if there is some type of data system. and attach to the window motor. you would be required to run two large guage wire and two normal guage wire into each door if using a dei 530t or 529t if i can help any further let me know maybe there is something i am not getting you can ask me via emial for advise.or aimJon

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.

On the master switch, on the drivers door the wiring is all ass backwards. I tested all the window wiring at the drivers door switch and here's what I found. drivers front up - Dark blue,neg at rest, pos when switch is pressed dn - dark brown,neg at rest, pos when switch is pressed drivers rear up - dark green,pos at rest, neg when switch is pressed dn - purple,pos at rest, neg when switch is pressed pass front up - light blue,pos at rest, neg when switch is pressed dn - tan,pos at rest, neg when switch is pressed pass rear up - light green,pos at rest, neg when switch is pressed dn- purple,pos at rest, neg when switch is pressed The switches on the other 3 doors have the colors as mentioned above PLUS each switch has a dark blue and brown which go from the switch to the motor. These wires do rest at ground just like the dark blue/brown on the drivers window. Does that mean I'm gonna have to run wires to each door to get the window modules to work right? I'd have to cut the two motor wires in each door and extend each(making it 4 wires to extend) and run 4 wires from each door up to the dash. Is there any way around this? and is this safe? Could I possibly wire up relays or something to the drivers switch to make it work?
