You will be removing the wiring when you swap doors either way. You have to put the 9C1 wiring back into the doors, because you do not have the cross car harness from the RM. If you get the cross car harness from the RM, it will include the rear door wiring, and that would require rewiring for your 9C1 switches. The outside mirror for the 96 doors is not mounted on the door, and you will have to use the 96 mirrors. I think the connector is the same.
If you are using the Roadmaster door interior, you are going to splice ALL of the connectors for the outside mirror, door lock, window and seat switches on both sides.
If you are going to use the 9C1 interiors, you are going to remove the two interior panel mounts at the top, install the arm rest support, and the nylon nuts for the straps. You may have to use the mirror control from a 95-6 if you are using the 96 mirrors and a 94 door panel, if the connectors are different.
The courtesy light has the same connector, but the speaker connector may be different. The mirror control switch for the RM interior panel may be different, or may just have a longer cable.
