New Wiring Harness, What Would You Add?

So I'm in the middle of putting in the Painless Wirring harness in the 74. It comes pre-wired with 8 additional pre-run and fused wires. 4 are constant power, and 4 are switched power. Everything needed to run the Bronco including radio and aftermarket Tach wiring is already there.

If you were starting from scratch, where would you run the additional wires and for what accessories?

I know I will be installing an electric fuel pump eventually and possibly a back up camera. Other than that, I'm pretty much open to suggestions.

What would you do with the extra 7-8 pre-run wires?

Will your electric fuel pump before fuel injection, or carburetor?
If it’s fuel injection, the power to the pump usually comes from the computer, not the chassis wiring harness.

I'm modding mine to have relays for high beam and low beam lights, relay for the blower motor, and relay for the switched efi power. Basically take as much load off of the ignition switch as possible. I'm also putting in a 6 switch panal for any additional lights...interior, fog lights, rock lights, etc.

Great point. I'm leaning towards the ProFlo 4 set up, but not sure about reliability and parts availability if it has issues.

My first thought is CB or Similar hard wired radio communication (considering the music radio is already wired in)
Will be running selectable lockers (just not sure if they will be electric or ARB)
Rock Lights
Possibly a light bar or "Lights" front and back.
Interior lighting for passengers, not necessarily overhead (thinking LED strips above wheel wells).
No need for a fridge, this is not going to be an overlander set up... But I could use a really nice cold place to store adult beverages:D
USB ports for sure

Pretty much open to suggestions on the must haves.

besides USB’s I’d put a couple of SAE connectors on the back. Very universal for fridges, lights, air blowers for water toys, air mattresses ect. I had to add one for my RTT. But used it for my weed sprayer, even plug in a battery tender.
