Re: J12 plug on mfc-01
take the coupler switch lead with MFU connector on the end.
cut off the switch.
solder the green and black wires together on the side with the connector, remember to insulate the join properly. best way is to use heat shrink tubing.
plug the connector back into the MFU, so that the MFU pins for J12 are now shorted together. This simulates the condition with the coupler switch closed, which happens when a trailer is connected. The MFU will deliver power to the motor accordingly.
