That's a good question... The theory makes sense (that any year VX can use the 92 ECU plus 5-wire sensor) but I do not know if that is the case... potentially the wiring could be different (beyond the 5-wire sensor) so that the 92 ECU is not plug-n-play on a later VX. You could probably find out for sure by checking out a wiring diagram for a 92 and comparing against a 93 (you may be able to find these on-line).
