This conversion is using as much stock Ford components possible. This includes all electric fuel pumps, tank switches, fuel lines, mounting brackets, etc. If you need to read up on what to get from the donor vehicle, then go somewhere else for the basics. I am covering a conversion using readily available parts in hopes of looking like a late model factory install when finished. If you bought a donor car for your conversion, that is a step ahead. I pulled the motor from a boneyard. It included all possible wiring from the ECM to everything connected under hood back to the main connector plug thru the firewall. Also the wiring connected to tranny and fuel pumps. With some good choices of parts offered over the years, I will make this conversion blend in to the existing workings of the vehicle. I am also including a Power Distribution Box for the efi and to upgrade any of the old wiring that draws a lot of current. Below is a part of the wire loom pulled from a donor 91-93 T-Bird/Cougar. Basically same as 94-95 Mustang. Its a MAF unit that shouldnt need too many alterations. But I will be adding relays and other components to splice wiring into the Bronco. So after scouring the boneyards a few times, I came up with a few possible power distribution boxes. One thats common to find is from a later model Explorer. I think all of the ones I have seen are rectangular, but the particular one uses the later style Ford relays that are compatible with generic Bosch style. It will hold six relays under the cover. A lot of available fuses and fusible links. You could make use of all 6 relay slots if wanting to route the headlights and horn thu the box. Earlier boxes have older style relays located under this box and not the one I wanted. Two other boxes I liked are from Lincolns and Crown Vics. Not all of these are worth grabbing. One version has a smaller square cover and holds 4 relays, 7 small fuse slots and about 10 fusible link fuses. The other I saw mostly on Lincolns had a larger rectangular cover and box underneath was more triangular in shape. This one holds 5 relays, not nearly as many large fusible links, but plenty of small fuses. I favor this one over the others. If hunting one of these down, make sure all of the relay slots are wired. Many I passed up had only 2 or 3 in use. These boxes are cheap and plentiful, so wait until you find exactly the one with all of the components. If you end up using all of the relay slots and still need more, the same vehicles with other remote boxes under hood with 2, 3, or 4 relays by themselves. Just run power thru fuse on distributin box to relay, then to load.
