I have a 2006 Suburban 4WD Z71 5.3. I need help hooking up wires on abs module. I have 6 individual wires that plug into holes on module. There are 2 red wires, 2 black wires, 1 green and 1 blue just hanging underneath. Need to figure out which wires go to which hole. Would appreciate any help I can get, Thanks.

Check your RPO codes, do you have code JL4?
Just to make sure we're looking at the same ABS system. Are there 2 connectors? A 2-wire and a 16-wire(hole) connector. If not, how many are there?
Which holes are empty? There are multiple wires with the same color.
The RED wires may be from the under-the-hood fuse block, check for 12V coming from fuses "ABS" and "VSES/ECAS"
About the blue and green wires, are they 'LT-blue/green' or 'DK-blue/green' ?

I will upload pictures of wires. In one of the pics you can see 16 wire plug towards back of vehicle. There are 6 round holes 3 x 3 towards the front the 2 front holes are smaller so i assume that is where the lighter gauge blue and green wires will go. The black and red wires are much heavier gauge and would have to go in 4 rear holes.

Not sure if plug was removed or if wires are out of back plug. I am sure there are 6 hole in abs module and 6 disconnected wires. Not sure what RPO is. Thanks for any help you can give.

There should be a plug on that 6 hole connector that the wires will insert into.
I'll need to know how the "holes" are labeled to help decipher which schematic to use to help you get this right. There should be letters or numbers molded into the plug. They'll be small and next to impossible to see.
The RPO code is a list of options installed on you vehicle. It's just a sticker with a list of 3 letter codes. Usually in the glove box or on a door/door jamb.
