I think i am going to use the canbus harness, just have to make sure the wiring is the same. I will have to change the 8 prong JST connector, female to male and cut off the triangle display fitting and splice on the circular fitting. I just have to test to make sure all the wires are the same. Green bike kit sells the 8 pin connectors, just have to solder the wires to the pins and make sure I get the order correct!!Ridetoglide,
Thank you for the info,
I am doing the same thing, changing over to the Uart motor, just for the programming aspect.
I stated to pull my motor for the second time and found out that the battery power cables had a thin wire soldered to the connection battery plug and I could not find out where this thin elect cable went to or attached etc. (Pulled the top battery connection, 4 pin plug to see the wiring.)
So I ordered a snake camera camera to go onto my Samsung camera, not here yet, then I can see down inside that main down tube, (I have a Wart Hog MD 750) same bike as yours, the camera has not arrived yet.
I ordered a 4 connection plug, main wiring harness and was sent a 5 connection plug, (I believe that the 5th plug is for lights etc. I don't know if this makes a difference).
I could pull/move the main harness cable, I did hit a tight spot, tied nylon twine to fish back into the proper place, and did not want to force it, reason for the snake camera attachment etc.
I also bought the same Uart parts as you did, do you really need to change out the speed sensor?
All the other parts I can see changing. And you are correct, there is NOT a lot of room between the frame and motor casing for all the wiring that passes thru there etc.
I am going to check the motor and add a good quality Corn Head grease to the gear train before I install the Uart motor back etc.
When everything is working OK, I plan on following Jon A setting has he and I do the same type of back country riding, off road and cow trails etc.
Thank you,

Alright, I purchased a Bafang cable and connected to the controller. Here were my settings. Of note, my low battery cutoff is set to 41V. I'm not certain if I'm in the "bike dies at 46v camp" because I don't think I've taken any rides long enough yet, but now I absolutely need to do a range...electricbikereview.com

You will need to change the speed sensor, the canbus speed sensor has 4 wires and the uart has 3.
I did notice an additional (smaller) power cable connected to one of the main battery cables and have no idea what it is for.
The Uart motor is a 1000% improvement in smoothness and performance. The canbus motor i had was very powerful but the bafang factory programming was HORRIBLE!!!
I will need to adjust my programming over time, I accomplished about 70% of my desired changes. Right now its seems i have to peddle hard to get it above 90rpm, the bike seems to have a lot of power between 70 to 80rpm and wants to stay there. I may have to adjust StartKG and FullKG at speed60 and speed80. And also base voltage, it is at 500 right now i am thinking of lowering it to 300. I already increased ReturnKG (from 5,4,3,2,1,1 to 11,8,6,4,2,1) to lesson some of the ghost pedaling but the results seem to be marginal if any which is ok, i rather have some ghost peddling than have to motor cutout constantly like the Canbus did.
Overall I am very happy with the Uart swap. I am going to take it onto the beach later on this morning to see how it performs on the sand.
