Jon,
The wiring is pretty basic. You need to find a good ground or make one off an engine or frame bolt. You also should have a fuse in-line with the hot side of the PC, so if there are any tuning faults, you can easily pinpoint the problem, if it is the PC or the base reference is the stock bike and how it fuels the bike back to 'base tune.' Meaning, if you remove the ground, the hot is still drawing a resistance in the injector wires. If you pull the hot side of the PC, it is much faster to diagnose IF there is a bad ground.
If you find downloading one map or say you keep pulling out one map after the other [on line at the PC's website], there might be on map that will feel better than the rest. Other than having a dyno set the parameters and dial-in your bike for that custom map [for this bike], you are handcuffed to the maps out there to try.
I have no clue how many wires are coming out of the PC, but if there are 6 wires? 4 go to the injectors. Say out of the 4 wires, 3 have the same color, 1 is different, then the 1 color wire goes to #1 injector is my guess and the other 2 wires are hot (+) and (-) ground.
Because I am not with product, I cannot help further other than what is basic setup of the wiring. You may have others with your mods and if their map or if there is a map to download here, you really cannot damage the bike per say, being it is more rich than lean.
