From everything I've read, there is a possibility. Any mod engine swap should have the same wiring harness as what was with the engine. If you put a 98 in a 96, you need the harness from the 98. This is because of minor changes Ford made within individual models and years. If you are PROFICIENT in dealing with wiring harnesses, you probably could do it. But that can be a lengthy and time-consuming job.
I've done a few swaps and had to make my own harnesses. It ain't fun.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.
1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.
13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane
I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter
.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos

Thanks for the reply, i plan on using just the block/ heads, just stripping off the intake and injectors and such because i believe ive thrown a rod, so in your opinion, think i could get by with that and still be okey with the 1998 wire harness?

im doing the opposite swap i have a 97 and am putting a 04 motor in from a decom CVI they changed it from two coil packs to i believe individual coil packs in 98 so that makes me believe youll need more than a harness in pretty sure they programmed the ecu diffrently, they also changed the transmission if you plan on juastusing they block and a heads im almost positive it will work but electrically im almost certain it wont
