I have a D04RKH9PW7ANSP01.

I received it with the remote head, and want to put the head right onto
the body for dash mount.

I took the head apart. The housing is HLN6432B and the back of the
face is HLN6396F (on the circutry).

I took the double 25pin faceplate off the body (HLN6344E) and it
connects to the body with long pins.

How can I get this head connected to the body?

Any help would be appreciated.
