Adding Fuse Box


I'm in the middle of taking the car apart getting it ready for a bunch of new items to install and I was just wondering if I should add another fuse box?

New Things being added:
Dual Ford Contour Fan
DCC Control - has built in 85A relay
Electric fuel pump - bought relay already based on one of my other threads

Already have my headlights set up on a relay from a company that I don't remember as I did it a number of years ago.

Thoughts on this or what would you suggest?
Painless Performance: CirKit Boss®™ Auxiliary Fuse Block/7 Circuits

If I go with the above or another one, can you use a relay for things after the intial one in the block itself?

I'm sure some of you have put in "extra" fuse boxes?

I don't know how difficult that will be, but you will like having that added protection. My AAW kit is nice because nearly everything electrical on the car is fused. I don't worry as much about electrical fires.

It should not be hard to add an additional fuse box.

I installed one of these (mine is a 6 fuse) where my battery should be.


Picked it up at oreilly's and built some nice supply wires. Double crimp with shrink tube.

I ran a few new wires into the cab. One carries +12 in on a heavy gauge wire, 1 is from the Ignition circuit. I added two relays (one for run and one for crank) and eliminated my fender mounted solenoid (My ministarter has one built in).

I did most of this when I installed my duraspark system (which is AWESOME compared to points BTW).

I plan on adding a circuit for an electric fan but right now 2 of the 6 positions just hold spare fuses. My car is built to drive, not really for show.

I installed that exact box into my car. Yes, you can use a relay post box. I've used an additional relay for my fuel pump.

Although there is a relay included in the setup, it controls 7 circuts. Being A-R at times, I added one for the pump.

It's a quality piece. You'll need a connection from the battery and then a tap into the existing fuse box to trigger the ignition hot wires.

I used that same box on my car as well. Pretty easy hook up as DrStang said.

I added one beside the solenoid under the hood. I have a lead coming form the solenoid to the little box, and I'm using it for headlights, fans, etc.
