I am wanting to add another small fuse panel in addition to my OE fuses. My plan is to leave all OE circuits as is, but will need to add an electric fan and fuel pump.

What say the FABO electric experts?

Thank you!
 
Never mind all. I posted before I “googled” but have info now.
 
Depending on how it's wired, separate fused wire from alt/battery to fuse box and go from there. Real simple to do.

If you want to bounce ideas, shoot me a PM.

Be careful of googled stuff as it may be for cars that have decent charging system wiring, unlike the ammeter stuff in our mopars.

Got the fuse blocks from Amazon. One is switched power and the other unswitched. The led next to the fuse comes on if the fuse is blown and there's a short. I made this panel to clean up my engine compartment. It mounts under my dash and moves my Mallory 6AL, voltage regulator, starter relay and wiper motor resistor inside. The feed for this panel runs through a 30 amp circuit breaker located low in the engine compartment.

Looks nice!

Is the bottom fuse box in the picture hot all the time (un switched) and the one above switched?

Also it looks like they are both fed off the same relay? Is that right?

The one is switched and the other is unswitched. The small relay in the picture feeds the unswitched fuse box. Power comes from the 30 amp circuit breaker in the engine compartment and goes to the unswitched' fuse box and to the common.terminal of the relay. When the coil of the relay is triggered by the ignition switch it connects the common to the normally open contact of the relay feeding the unswitched fuse block. If it will help, I will make a schematic diagram and post it as soon as I can just let me know.

That would be great. What do you mean when you say un switched?
 
Here is the modifications that I made. Running the voltage regulator off of the relay eliminates the voltage fluctuation that causes flickering lights (caused by dirty/worn ignition switch contacts) is optional. If you have any questions, ask away.

Here is the links to the 30 amp circuit breaker I used and the fuse blocks
