Wiring harness circuit plan

JSmall · Apr 17, 2019

I'm planning out my new harness right now and I would like to know if I'm missing anything. Excluding the normal items that a harness would power, I have come up with this list. What "extras" do you guys have that I may have missed?

USB charger - Switched+
12v power plug - Battery+
Tablet charger (12V to 5V inverter) - Switched+
VHF radio - Battery+
CB - Battery+
Line lock - Battery+
LED whip - Switched+
LED rock lights - Switch-Pro
LED backup light - Switch-Pro
LED driving lights - Switch-Pro
Driver heated seat - Switch-Pro
Passenger heated seat - Switch-Pro
ARB compressor - Switch-Pro
Front ARB solenoid - Switch-Pro
Rear ARB solenoid - Switch-Pro
Winch - Battery
Amplifier - Battery

Hey Jaromy. what, no on board beer fridge / inverter

on a serious note, you might want to consider bed area lighting. i will be installing LED strip lighting under each bed rail for some light in the back. i'm running a switched power leg to each side to a switch and USB charger port as well as a switch for the strip lighting. port and switch will be on the back side of speaker pods tucked behind b pillars.

dome lamp?

Good idea. I plan to have the interior LED lights controlled by the stock switch right now. I can add a rocker switch to control the rear lighting.

No on board fridge for now ;D

How about under hood lighting? Always nice to see when you have to work on it on the trail late at night. Having it switched under hood is nice as well.

i seem to recall that the FJ40 i had back in the day had some sort of under hood light on a retractable cord (might have been a different vehicle). some sort of weather proof plug under the hood might be best with a detachable LED lamp on a cord that can go right to what you want to see, not create a god awful shadow over what you want to see because its in the wrong spot. certainly cleaner than clamping leads onto battery terminals

Ford had those in F series trucks for a while.
Not too hard to find, usually sell for about $30
The light bulb part has a magnetic base.
The bulb is a fairly common size, you can get an LED bulb for a few dollars.

Trans cooler fan
Dust light (Rear facing amber light)
Transfer fuel pump to pump fuel from aux tank to main tank.
Rear 12V power plug for ARB

What years F series, do you know?

Electric radiator fan.
future circuits for fuel injection?

Good idea! I have rock lights and I planned on doing something like that, but forgot to add it to my list. Thanks!

Running a ZF 5 speed
I have that listed as a backup light. It will be a standard small LED light bar
One 20 gallon tank in the rear
Not sure what you mean by power plug for ARB. I have the compressor in the engine bay right now.

Thanks for all the suggestions.

I should have added my complete list...my bad. I have an electric fan installed right now so it’s on my list. I just installed an Explorer 5.0 so I have a stand-alone relay box for that stuff.

By "power plug for the ARB" we might be thinking ARB Fridge/Freeze. Gotta' have one of those after all!

And what about a second battery? With all this cool stuff, much of which is connected to full time power without the ignition switch, the opportunities to drain the battery overnight from leaving a radio, or some other device (like an ARB Fridge/Freeze!) would not leave you a happy camper in the morning.
Been there, done that. But always with a backup plan...

I really like the not-so-simple, but effective isolator relays that let you jumpstart your own dead battery with the second battery if it comes down to that.

A 2nd battery is a good idea. I can move the radiator overflow and have plenty of room on that side.

And then you will be balanced ;D

Nice work as always...

1980-1986

The cord is long, it will reach all the way to the back of a Bronco, which is why I consider it better than a fixed mounted light.

I had an 84 Bronco with that light, it was great. I wish someone would make an aftermarket one like it.

google-fu yields GM 15528774 and GM 1599293 are the two part numbers that GM used for their version of the retractable underhood light in case you are interested.
