The test drive was awesome! This thing flies compared to when it had the 302 and C6. It even leaves rubber across peak torque in first gear. Skurrr!...

We were adjusting the shift linkage when a cloud of stinky smoke came out from under the hood. We feared the worst since it looked to have come from around the firewall area and tracking down a wiring issue that would kill the PCM would take forever. Luckily, we noticed strange orange burnt particles near the coil packs and we then realized this coil pack had spit its guts out the bottom. The key had been "ON" for about an hour while we were working on the linkage but I have no idea why it would do this, unless maybe we cracked it while making the coil bracket. We swapped the coil and put in a new fuse and she roared to life! ...

The finished product! It turned out fairly clean but it sure would've made sense to paint the engine bay before we dropped the 5.0 in. Learn from our mistakes!...

We had cut a section out of the throttle bracket at the bottom and weld it back together to clock the bracket down so the cable didn't point up into the hood brace. It did reduce the throttle travel so that the throttle body only opens to 88% of WOT. Probably fine but spacing the cable out from the bracket 1/8" or so could get this back to 100% if deemed necessary....

Arial view of the PDB. These wires now have split loom protecting them. To the right of the PDB you can see C123 which has the Yellow/White PDB constant 12V wire to the alternator and the Lt Green/ Red wire that goes from the alternator to the dash charge light. This connector is 4-pin but some models had an 8-pin version....

This still needs a little cleanup but it's just a busy area for wiring. C115 splits into 3 groups here:
-The 7 factory circuits to the PDB
-The wires through the firewall to the dash area
-To the passenger fender area: the 3 C115 ground wires, RUN wire from the old voltage regulator to C115, and big ignition switch black/yellow wire that splices to the big yellow PDB wire.

The rest of the rainbow spaghetti is just the wires from C115 to the engine and from the engine to the PCM that's mounted in the firewall and none of those are touched....

The Explorer starter solenoid coil grounds through its case so we removed the paint from the wheel housing underneath it. Also grounded to the mounting stud are the fuel pump, PCM relay, and RUN/START relay. The green ground goes to the ODB2 port. I don't trust the ancient Bronco body for grounding duties!...

Since the Bronco doesn't have a true RUN/START circuit from the factory, we created one with a bridge rectifier and a relay. Two individual diodes would work instead but the bridge is easy to mount. The diodes keep the RUN circuit from activating the START circuit and vice versa. The only thing that needs RUN/START power is the Red/Lt Grn wire that feeds the PCM relay in the fuse box and the ignition coils via C115. ...

OBD2 port (AKA DLC) for diagnostics. It has 3 wires from C115 and then a power and ground wire. Laying on the floor are the check engine light wire that we didn't bother hooking up and the tachometer wire for future tach use. Both are from C115 behind the engine....

This is the alternator charge light and it does need to be a bulb rather than a LED, preferably with a 470 ohm resistor in parallel in case the bulb burns out....

Overdrive cancel switch and LED. There was a big hole here already so in it went. The LED has a faint glow even when not activated so a bulb indicator would be better. A series resistor would likely also work....

These 3 connectors were originally in the engine bay.

The 4-pin square connector is used for the black/red wire to the reverse lights and also the red/blue START wire from the ignition switch. The other two wires are capped.

The 3-pin red connector (C-21 is used for the Grn/Wht wire to the oil pressure gauge and the Red/Wht wire to the temp. gauge. The heavier wire is not used.

The single pin connector is RUN power used for the alternator light, overdrive switch, and overdrive cancel LED.

The orange and green wires running horizontally are the 12V and ground wires for the OBD2 port....

Nearly finished. We were going to keep the A/C lines for potential future use but we're going to yank them since they clutter things up. A little more wire management and it'll look pretty nice!...

The oil filler ran into the intake tube and I just happened to have a Buick 3.8 sitting on the shop floor and its lower radiator hose was the perfect size to fit the filler tube! It had a ~45 degree bend in it and it worked perfectly. We rarely get this lucky cobbling stuff together! The hose specs say it's 1 9/32" diameter and it should be a Gates 22373....
