I attached a picture that points out where the release tab is for the harness that plugs into the Prodigy P2 part # 90885 that you have. You have to pull up on it so that the harness will separate.

I have a DX3 Motor coach it has the prodigy P2. I know by the display o.9 I have a ground problem. I looked around the battery area and saw no white wire went to the area of my seven way and nothing resembled the white wire from the Prodigy P2. Lots of white wires. Need a service call?

@Dean There really should be a white wire coming from your P2 that goes to a solid ground that could be the negative post of the battery. So you are going to have to check the wires that come from the P2 and find that white wire and see what it is attached to and trace it back to where it is attached and improve that.
