    Dont laugh, I dont dabble in vehicle wiring that often :eek: I'm much better w/ more mechanical shit, lol. BUT, as I plan ahead, and in an effort to keep the setup clean, I want to add a fuse block setup. Can you guys help out? Does this look right? What can/should be added to this? Anything? Should I go back to the battery or use a ground on the vehicle for the ground coming out of the block? And whats the general rule of thumb for fuse sizes? For instance, my 2 oznium LED under hood lights. What size fuse would be best if they're 1watt each (Current (mA) 154.7).

    Hope this doesnt sound too elementary of a question. I just want to make sure I'm getting it right. :)

    I did :( I guess I pretty much understand how to get the proper fuse sizes, but that thread kinda loses me as it gets more invovled w/ the relays.

    From what I'm seeing though, the ground from the new fuse block should go back to the battery, correct?

    Once it comes to switching lights up front, I'll have to dive deeper in to relays. I pulled this diagram from a different site, which, like the diagrams Larry posted, are helpful as I gain a basic understanding for the wiring.

    First off, you probably don't need a negative buss. Blue Sea makes fuse blocks that don't have a negative bus. I'd suggest you use a factory service manual to locate factory ground points and use those rather than running ground wires back to a fuse block. Here is an example of a fuse block that does not have a f negative fuse block: http://bluesea.com/category/5/21/products/5034

    You can place your fuse block in a plastic project box to keep the dust and water out and have a more professional looking finish. Here is an example of that: http://www.ttora.com/forum/showthread.php?t=67738

    For fuse sizes just learn what Volts, Amps, and Watts mean and how they are related. Then you can figure out what fuse you need without taking anybody's word for it. A related topic is choosing the right gague wire.
    Here is a link to a wire size calculator (scroll down almost to the end of this page) http://www.bcae1.com/wire.htm It helps to read the explanation when using this calculator.

    Lastly, consider using glue impregnated heat shrink and split conduit tubing for your connections and wire runs. This will help prevent lose wires and abrasion of wires that can result in short circuits or fire.
