Lots of good info posted. I’m doing this on my truck as we speak, I’m using a switchpros rcr 12 for pretty much everything accessory and a 96 way gep box to hold the stock PCM and fuel pump relays etc.
A switchpros is just a PDM, power distribution module. There are a lot of PDMs available but for the money I think switchpros is pretty solid.
When you want to go a cheaper route, you can build your own using a blank fuse box. You could go on eBay and buy a pre wired box with terminals etc. Thing with those is they’re usually made like shit, horrible terminal crimps and the bus bars/terminals doing weird shit under high loads.
If you did go the “cheaper route” and build your own a quality bussman or gep box would be ideal. Gep is a blank box, busman has different models and different bus styles for like relay side, fuse side etc. Gep boxes handle higher loads better than busman with the bus bars built in. Gep boxes use tanged terminals along with a tanged box, opposed to the busman having the terminals built into the box, but tangless terminals so if you break that terminal retainer in the box, that position is now useless. Each style has gives and takes.
But honestly after everything I typed, the price and time to me honestly isn’t worth it. The amount of tools you would need to do what I said isn’t even worth it to the average person. I’d rather buy a switchpros, a bag of 14g-step up/down splices and some heat shrink and just be pretty much done with it. The time and money involved to do a fuse box style correctly, maybe just use it to save for a switch pros.
