Default F150 different year 302 engine swap problems

Hi. And thank you all for the welcome to truck forums. My question is and any answer will be much appreciated I have an 86 f150 with 302 EFI that I hydrolocked so I found a 302 out of a 93 and put it in my rig the problem is that my original engine had the multiple belt system and the 93 engine is serpentine belt system so wiring harness and hook ups are all different and I assume the PMC as well. I don't have the 93 harness. Can anyone give me advice on the best way to get her up and running. I guess what I'm asking is can I change out my pullys from the 86 onto the 93 and use original harness or should I get a 93 harness and try and make that work?
