Folks choosing to connect this way will need the programming cable. They also either need an adaptor cable or just cut the end off the cable and wire directly to the 20-pin connector. This cable will plug into the cable that comes off the display and allow you to program the Metacycle.
Votol EM200-2SP Programming Cable
Amazon, AliExpress, and eBay have these. Lean more about this item.
20-Pin Molex Connector
Amazon supplies this part and it comes with pins you crimp onto wires. You'll want the female end, as pictured here. This will attach to the cable on the bike behind the display.
4-Circuit Connector (Optional)
Amazon has a kit that has a piece to connect to the programming cable if you want to keep your cable intact. This method is what's shown in the video. If you want to save a few dollars, loosen the screws on the USB adapter and pull out the wire, then use your own wire to hook up to the 20-pin connector.
The video shows how the programming cable was kept intact and an adaptor cable was created.
The comments indicate that the wiring diagram is wrong. Make sure the adapter's hooked up this way:
TXD → Pin 1 (CAN-)
RXD → Pin 11 (CAN+)
GND → Pin 20 (GND)
This is a diagram showing the 20-pin connector's pinout. It is pictured as though you are looking at the display unit.
Make sure you do not use the diagram from the video. Below is an image that shows the corrected pins, from a Facebook discussion. Also, Burt shows that only pins 1 and 11 need to be connected.
After building the cable, you can use it to program the controller.
