I have a 2001 silverado 2500hd 4x4 (electric push buttons) 6.0, 4l80e auto trans, i just recently bought, and it came with no transfer case (it was apparently stolen). So i bought a transfer case off of craigslist from a 2003 2500hd with the same push buttons on dash for the 4x4 same motor and trans as well, I went to put it in and it fit perfectly , everything lined up as it should of. But the plugs on the transfer case motor does not match , as my factory harness has two plugs , and the transfer case i bought has one flat plug, is there a adapter to make this work, or if i buy the right transfer case motor for my truck will the bolt holes line up and work? Thank you in advance
