This version of the SPARK MAX CAN Cable bridges the H and L signals together. By doing this within the cable itself, the CAN Bus is less likely to break in disconnection from the SPARK MAX Motor Controller. One end is the JST-PH 4-pin connector, with the other splitting to one male and one female 0.1 in. 3-pin PWN. The CAN High is on the yellow wire and the CAN Low is on the green wire.
