TSDZ2B 860C display confusion

[Mike_Kelly]

Gathering materials and researching I decided on the TSDZ2B OSF with the 860cc display. But what is confusing is that there appear to be two (or three) versions of the 860c. One is the version made for Bafang with either a UART Higo connector or Canbus connector. Then there is a version touted as being for the TSDZ2B with a different 5 pin connector. It is all black unlike the color coded Bafang style. The ads indicate that it is converted for use with the Tongsheng.
I plan to use brake sensor levers so since the 860c does split out connections for throttle and brake sensors I decided I could use an IT4 cable to split out the throttle, brake and display cables.
My TSDZ2B kit came with a 860c with a Bafang style Higo green color coded display cable. But I received multiple IT4 cables. One Bafang style and one with black connectors.
So the question is are all 860C displays the same with different connectors? If I have an IT4 that connects to the 8 pin TSDZ2B motor connector and has Bafang style color coded ends and an 860C with the same color coded connector will it work with OSF for 860c or must I have all parts made for Tongsheng with an 860C made for the TSDZ2B and a matching IT4 cable? or is there no way to use an IT4 with the 860c to add the brake levers?

You bought a complete kit? Or pieces?

If it's a kit, put it together and test it as is before touching anything.

Then look on back of your 860c for the model/version number.

The kit came with parts that don't seem to work together. It has a 860c with a higo 5pin green connector but the 1T4 cable with the black connectors do not connect to the 860C. The Bafang version 1T4 does not connect to the motor, 8 pins but reverse connector M/F.
I finally found an IT4 with bafang connectors and the correct sex connector for the TSDZ2B motor. Will see how that does.
I can also see that the standard cadence sensor is probably not going to work on my fat bike frame because there is just too big a gap between the sensor and the magnet. I wish somebody made a disk rotor sensor like on my M820 bike, but it is canbus.

Wired are wires. If the "kit" doesn't connect, then it's not really a kit. Kinda sounds like you got ripped off.

My motor had reverse m/f, so I had to chop off the connector from my vlcd5 and wire it onto the tsdz2 motor. This involves a multimeter and a pinout diagram.

I used a ttl to flash the display and a stm programmer to flash the motor. This also involved chopping and making wires.

You need to figure out what you have, power up the display and see what firmware is on it.

Your motor is 8 pin throttle right?

I have done that and got the T shirt. But I would rather have the proper commercially made cables. I am not interested in the old VLCD5 display. To use the 860c with brake levers I need an IT4. There are three different IT4 cables out in the wild. The one for Bafang, which has the wrong sex 8 pin connector for the motor. A Higo cable with all black connectors which will connect to the motor but not to the 860C. So I found the right cable from Electrify Bikes in Utah.
The documentation available on the net does not identify that there are multiple connectors involved with the TSDZ2B. It is a waste of time. The Kit I got came from the Tongsheng retail supplier.
