Sure, let me know what you need and we can figure it out!
What surge tank do you have? I used Edelbrock fuel sump (36031) and I’m happy with it so far. Fits nicely under coolant overflow bottle, it is quiet and has a built in pressure regulator with vac reference (having intake vac reference is important for MPFI, unlike TBI). Bracket for it is basically couple aluminum strips riveted together, plus some rivnuts to mount the sump
As for harnesses, it depends on what you need - I have planned to use bussmann relay box for all added fuses and relays even before I started thinking about ProFlo. And I just don’t like inline flag fuses dangling around or relays screwed to body metal, so I cut them out of PF4 harness, added a metripack connector and put main relay and fuse into bussmann box together with others.
I also shortened leads to surge tank (it was couple feet too long) and got rid of extra connectors there.
Finally, I took stock engine bay harness out and inspected all wires. I replaced factory Jeep splices - they were corroded (Jeep used regular duct tape to wrap them), so new splices and marine grade heatshrink over them. Removed all unused wires - mainly ignition (PF4 is replacing Duraspark box as well), carb/emission circuits (throttle and carb bowl vent solenoids, choke heater and oil pressure switch wires) and exciter wire to the alternator (I’ve replaced stock one with 150 amp powermaster unit which doesn’t need exciter wire).
Another unnecessary, but useful mod was cutting the harness going along driver fender to front lights, horns and washer pump and putting watertight connector there - I prefer more modular harnesses, so I can either take parts out for repairs or easily disconnect circuits for troubleshooting.
So most of my mounts, brackets and harness mods are either specific to my setup or my approach to wiring things, keep that in mind. Some things, like ECU mount plate, are more universal and don’t depend on other things
