Don't really have much more to do, I have about 8 wires to marry into the standalone harness which is other wise all plugged in, then I have the starter to do, figure out how in the hell the a/c bracket gets put on, start hooking up hoses, and from there I'm in the homestretch.
Right now I'm waiting on a driver side battery tray...wasn't able to find one used at any junkyards or online so I had to buy it from gmdirectparts.com
