In peeling back the outer cable sheath, you will find a copper wire wrap for strength down the cable, six colored wires, and an internal strength member. Some trial and error with one cell will lead you to quickly identify which wire is for which cell. Mark them. Now this leaves three unused wires. As it happens, the three cells share a common ground. Once the ground is identified, all 3 grounds tie in here. Clean it all up with some shrink tubing, and you're good to go. Double check mV's on the computer to read 10-13mV. Also double check that the cells are properly identified as 1-3 by unplugging one at a time. I permanently ID my cells and corresponding Molex connector by melting small holes in each with a soldering iron. Ex. 1 hole in molex and 1 hole in teh top of sensor 1, to denote sensor 1, and so on.
