There are two versions of the florescent tube display VIC, a two plug and a single plug I believe. I would get a FSM for your year and get some one to post the wiring diagram for the 1997 and do some comparing. Probaly not an impossible job but there are more functions with the tube display model which probaly means some circuit running. I put one in my 98 that didn't have one. I'm not familiar enough with the cross year diagrams to give you a go, no go answer.
