hi there! somebody gave me a durabrand db1200 with no wiring harness. i plan to only use this in my shop, so could anybody tell me which wire goes where? i noticed on the back there is a place for 12 wires, 2 rows of 6. can anybody tell me which wire goes with each hole, starting top left going to the right for each row? that is as you're looking straight on at the back of the unit. any help would be mech appreciated!! i plan on hooking each wire up individually!
