Hey everybody I'm in need of some assistance finding a wiring diagram or color coded diagram for this controller that I have I've already went through four or five different controllers trying to get them wired up to a bike on building which is in its own sense of Frankenstein to begin with however if anyone here could help me since I'm new at this figure out what each label is or each wire is and where it goes I would greatly appreciate it thanks in advance

The thick red and black is from the battery, the thick blue, green, yellow is motor power, the 6 wire connector is 3 motor hall sensors, a 5v positive and negative, and a white wire that is probably for a speed sensor. The other connector is for the display. The 3 cut wires might be for the PAS or throttle.

Okay awesome next question I'll be using a g51 display hopefully unless I find it the display wouldn't be compatible with this controller for whatever reason however it's going to be red black green blue yellow I believe on the display which of the wires on the controller in the nine pin cluster that you detailed do I connect each wire to obviously 5v+ going to red 5v+ and black to ground in that harness however the rest are confusing to me
 
The nine pin connector I don't know the details of. I assume the display connects in there somewhere. Don't have any idea if your display is compatible.

My generally universal suggestion is always buy a controller kit with the display, throttle, PAS, etc., that fits your motor's connector. Makes it much more of a plug and play experience.
