I am replacing the stock motors with a single Dewalt 820.

Should both sets of red and black wires coming from the EVX-2 be wired to the motor or do I just connect 1 red and 1 black wire?

I have seen a few u-tube videos where it looks like people have soldered 2 black and 2 red wires to the single motor.

The kit from Kershaw only has 1 red and 1 black connector.
