LED lights wiring

[NomeCrusher]

Okay, so here's my question.
I have a flip switch installed so that i can choose to turn on or off these aftermarket interior lights in my car, my only problem is i have no idea how to hook it up correctly.
The switch has three prongs
1.)Supply
2.)Accesory
3.)Earth Ground
How do i wire this, plus where would the positive and negatives wires of the lights run too?

Please someone help

supply goes to a constant +12V supply like battery or fusebox hot

acessory will go to the positive wires on the LEDs

ground will go to a good chassis ground on the car along with the negative wires of the LEDS

thank you, this helps alot.
i have 14 gauge automotive wire, they make a red one for positive and black for negative, does it matter if i use all red?

also on another matter how would i run the supply to the fusebox? does it need to go in through the back to run a fuse for it? if so how would i remove it?
is there some kind of pictures or another?

wire color is so you know what goes where you can use the same color but if you mess it up you are to blame not the wire

you can get a fuse ad in from placed like autozone...
theres a fuse box in your glove area theres a panel for it but its hard to say when the 97-03 is diff than a 04 and you didn't describe the car..

ALWAYS USE A FUSE!!! don't skip adding a fuse when you add your lights. If you need help with this project let me know because I am becoming a semi-expert on adding lights in cars now. I just recently put in lights in my ash tray and cup holder. I already have lights in my air vents and put in leds in the both the front and back where the feet wells are. If you need pictures I could send you some. On my switches that have three prongs the power one is going to be the one that u run from the fusebox (easier) or the battery itself. The opposite side should be the ground. The easiest way would be when you wire the ground to the switch to also combine the wires of the lights (ground wires) to the same prong. The middle one will be the power to the lights themselves.
