What engine for the 91 did you use to replace what engine in the Bronco? Do you have the diagrams of each to match the harnesses up to where they needed to be?

Jeremy. Thanks for working with me. I am converting my bronco which has a 302 EFI. I have rebuilt the engine and removed all of the EGR systems. I installed a cam and have added a mass air sensor. Since the bronco was originally speed density I have a pcm from http://www.mass-air.com/Products.htm that they make for the trucks. I think I'm going to just start from scratch with an engine harness and make a new one. No one sells a bronco engine harness so people use a fox body harness since it has the mass air connection. I really need to know what I absolutely must have to get it running. I've ordered new relays and connectors from rock auto. What do I have to have? What's optional? Do I need to re-pin anything with this pcm I ordered?
I'm an amateur mechanic but at this point I know more about mid 80s broncos than the average bear.
