Interesting bunk A/C find. Could use a little guidance.

2007 379 with 63" Uni-ultra. Bunk A/C relay in the bunk load center is missing along with a couple other relays. I can get a list of them if needed. Blower motor started acting up a little while back. Found that it had a bad resistor. While waiting for the new one to arrive I took the liberty of by-passing the old one so that the fan ran on low speed all the time as long as the key was on. Fan worked fine but I had no temp control. This struck me as odd but I figured I'd see what it did when I got the new resistor in. New resistor showed up and was installed. Pulled the jumper before I connected the plug. No fan. Pulled the control panel down and the fan started working. Raised it back up and it went off. There's a 14g green wire that appears to have been added at some point that is clipped onto a white wire marked "GND-A". The green wire is a short run over to an aluminum rib in the sleeper that is used for re-enforcement (and evidently a ground). Page 43 from Supermiller's '05+ 379 schematic shows that a yellow wire marked "YEL 7260-2" goes to the blower relay. From the relay the wire on the other contact shows to go to ground through "WHT 1130-90". Can someone point me in the right direction to find where this connection point is without me having to tear my sleeper apart? This truck runs daily and I'd sure like to get it like it should be as opposed to the fine feat of engineering that is there now. That little green wire Got pretty warm to the touch while I was messing with it earlier. Thanks in advance!
