Hey guys, I was wondering what wires I need to unplug. I have a 97 and there is no 4x4 control module in my truck at all? The only boxes are in the dash...one on right (rear abs control) and the one on the left (GEM) Down a little deeper on left side is a very small sqaure box (not sure what it's for). So do I unplug a harness from the GEM? I am also going to wire up my lights from new manual t-case for dash to work but not sure if unplugging the GEM will disable this from working?

Thanks,
Dan
