The VEC1 control module and air/fuel meter are the same for 1992 to 2002 Vipers. What's different are the wiring harness lengths, installation instructions and tuning instructions. Basically, 1992-1995 RT/10's are the same, 1996 RT/10's are unique and 1996-2002 GTS / 1997-2002 RT/10's are the same.
If someone purchases a used VEC1 and needs installation instructions for an earlier or later model year that the kit was originally for, just drop us an e-mail or call and we'll be glad to provide them.
