Chrysler Repair: 93 Overhead message center: install as after-market?

Question
Can I swap a 93 Chrysler Fifth Ave overhead message center to another 93 Fifth Ave that was not originally equipped with an overhead message center?

Thanks
Gary

Answer
Hi Gary,
I do have the '93 wiring diagram manual which shows the wiring for the visual message center, but it is also the case that there is a different body computer depending upon with or without message center, and with or without electronic instrument cluster. On that basis I think you would also need to change out the body computer and even then I am not certain there couldn't be some other subtle differences in the wiring that connects to three modules. So I would doubt you can pull this off without a lot of hassle.
