I've been trying to figure out how to install my fog lights... I've got hte lights on my car, they sure do look nice, but they're not functional.

I've seen a few good threads on it, some good diagrams, etc.

I wire up my guitars all the time. Very simple stuff, but I knew enough to get by there.

Im looking at this diagram:

Most of it seems simple enough, but I've never messed with car electronics in my life. Looking at the circuitry it's all very simple, it's the logistics that confuse me.

How exactly does one get a connection straight from the battery? Certainly it's not hard and there are a million ways to do it, I'm just not sure what the proper correct way is. Tap a wire you know is hot? I mean obviously shoving a wire down into the terminal on the battery will work but I doubt that's a good idea.

Secondly, I see the line from the fuse box. Also seems simple enough but a similar question, I've never messed with a fuse box before. How do you get a hot lead from it? Are there terminals you solder to or what?

I guess my background in electronics wears a little thin when dealing with active circuits. Guitar electronics are all passive.

 

Here's what I would do...
Wire as much as possible INSIDE the car. In your case keep the relay and battery wiring inside under the dash. I usually pull battery power from the bat terminal on the fuse block. I use a wire with a spade connector on the end & plug it into the bat terminal in the fuse block. As your diagram shows, always equip that wire with an appropriately sized fuse as close to the source as possible. If this wire is not fuse protected, a dead short in your circuit WILL cause a fire.
I protect all wires with plastic loom, especially wires running thru the firewall & in the engine bay. Make sure your connections for the lights are good & solid and seal them all with heat shrink.
Good Luck,
Corky

 

If you want to connect directly to the battery (it is useful sometimes) they sell a battery terminal at autozone that allows you to clamp other connectors to it.
