I'm having some heated seats put in, and I asked how they wire them up. The response was tap into a ignion wire under the dash and run a pwr wire from the battery. Seeing as this truck is brand new, I don't want to hack into wiring, plus I plan on installing a set of driving lights, reverse lights and whatever else comes along So might as well add a aux fuse block.

In my searches I'm finding lots of opnions, I thought it would be easiest to just add into the underhood fuse box, but according to a Chevy forum that is just asking for trouble. Chevy even has a TSB on adding a fuse block saying the relay or solenoid needs a diode to keep from back feeding trace amounts of power and hurting the computers. Is this true with out fords? I don't even know what a diode does!

What I want is a key on powered aux fuse block. I don't think any of my power draws will be big, seat warm willl be a 15-20 amp fuse, driving lights, bed lights, reverse lights all 5 and under I'm betting.

I THINK what I'm going with is a bluesea 6 accesory box, with ground bar.
The order of things confuse me, I know I need a realay for being key on power, some people say constant duty solenoid.
Then comes in the fuse or circut breaker choice.

Can somebody point me in a direction to help me learn and plan to make a setup that won't fail me or damage the truck? I don't think it matters but its.a 2014 f150 5.0

A cheap solution to a potentially expensive problem is to find a professional that understands all the electrical issues you are trying to address. Trust me, your expensive truck is nothing to learn on, especially when you consider the costs of computers and other sensitive electronics on our rides. No insult intended, just a suggestion.

If your going to use any of the blue sea stuff, make sure it is the marine grade components under the hood.

Here is a great source for learning about a lot of the concepts, and details:

It's targeted at the car audio world, but it's going to have a lot of serious overlap with what you want to do.

I think you're going down the right path, but a couple of things to keep in mind.

1. Does your truck have the battery monitoring system? If so, you want to make sure that your ground bar is connected downstream of the current sensor on the wire, or you're bypassing the system and could cause problems. Or you can route your connection to the battery through the current sensor.
2. If you mount the fuseblock close enough to the battery (say a foot) you probably don't need to install a circuit breaker or a fuse, as each of your branches will be suitably fused for your loads. Your call though.
3. If you use a solenoid or relay to switch the power for switching the entire block on and off, you'll effectively eliminate it as a source for constant power later. I would suggest you wire the fuse block as constant on, and use relays to switch the relevant loads when you need them. More wiring though, and it doesn't sound like you want this option

You're certainly on the right track, IMHO. You might be able to just get the guys installing the seat heaters to do this for you.

Cool,thanks guys. The down side of having someone else do it, and me being clueless about it, is if they actually know what they are doing. I'll have to check that website out. As for battery montinring system, I think I have that cause I left the radio on one day and it shut everything down on me.
as for being key on power, I want that incase a me or a passanger leaves the seat warmer on

I am going to do something like this on mine, I want to add lights and a few other things, But, I hate locating Relays, so I figure either make on or go find an older one in a junk yard and mount it.

Here's a setup I used in my old tacoma, but should be able to be reworked to fit an F150. Also, I'd keep the fuse box and breaker under the hood instead of inside the cab due to possible fire concerns.

^^ I found that link last week when I starter the search. Very clean. Imore thinking mount it on passanger cowl, just above the 3 plugs, or someone on here made a little bracket and put it right by the battery. I'm after function and clean.

What signal wire are you talking about, and by down stream do you me closer to the battery? I was planning on getting power from the post on the fuse box over radiator
