Hey guys,
I recently purchased a 1981 CB750F that came with an aftermarket speedometer included (Acewell MD52).
I personally do not like the style of the Acewell, so I am swapping it with this one:

The last owner installed a cable which converts the factory speedometer cable to a digital sensor, but it only has two wires coming from it, which is a Speed Signal (+), and a ground wire. Here is the wiring diagram for the MD52 speed sensor:
Here is the cable I'm referring to:

The new speedometer I want to swap to uses three wires for the speed sensor:
Speed sensor positive pole, speed sensor negative pole, and speed sensor signal
Here is the connector for the 3-wire sensor:
Is there any way I can convert the 2-wire connector to use on my new speedometer?
