You can tell what year it is by looking at the distributor cap.

91-94 will have 5 posts (uses an external coil)
95-98 will have 4 posts (uses internal coil)

As for your wiring don't cut the harness and use the old connectors. simply buy a swap harness to install a DOHC into your SOHC chassis.

here is a link to a well known reputable company: http://www.wiringspecialties.com/wsprs13kaeni.html

Most of this stuff is common knowledge and has been covered on this site as well as other forums, good luck with your swap just remember...search before your post.
