ok so i have a buddy who has a 4 channel rearend that i'd like to put into my 3 channel abs bird. i know the brakes are hat style and not intergal like i have now which is ok since i have the calipers and rotors. my rear concern is the abs. not sure what i should be adjusting (if anything) with the swap. anyone who has a 4 channel ls bird know how it all connects into your abs module? does it have 4 lines leaving the module? mine has only 3. any help would be freaking awesome.

p.s. sorry i haven't been on to help out. been busy working to pay for the engine i'm putting in.
