Ok, cool, so I read a lot about stuff while at work last night, and yeah, what you're saying is right. For some reason i started worrying about the amps, volts and watts and how to adjust the right settings for each component. But whatever is built to be used in a car can technically just be hooked up and ready to be used.

All a person has to worry about is the type of wire you're using, and watching your amperage so you can determine what strength fuse, relay and switch to use.

So, I'm all set!

 

Also keep in mind how the wires are insulated and secured, you don't want them to corrode or get pinched and create a short to ground

 

unless you are running about 8 sets of 150w lights, I dont think anything will have any problems using 12-14 gauge, depending on how many you want to run.

If you are going to run a lot, use an 8 gauge line to the D-Block, and then 12-14 from there to each set.

An inline fuse in the 8ga, and one in each of the 12-14ga, just for safety imo.

you never know what can happen on 1 set of lights that can affect all of them, unless each is isolated by its own fuse.
