Hello, I'm just wondering what I would wire 2 6 led bars to if I want them under the seats of my base cavalier? Also, how would I wire them to a switch? Thank you!

step 1- tap into fuze box with a power from the battery-this allows you to fuze your system to avoid fire
step 2- run power to a switch in desired location (mine is a stock looking switch on my window switch cluster)
step 3-ground switch
step 4- run an ignition wire if you only want the lights to turn on when the car is on.
step 5- run the power out on the switch to your led bars.

The switch itself should have three prongs on the bottom, one for power one for ground and one power out... it usually says it on the switch.

Its pretty easy, just make sure you take the time to either heat shrink the connections or sodder and tape... heat shrink works best

Some switches only have 2 prongs. They are more like power interrupters, I prefer to use those. In which case you do use 2 prong switches then run power line from led bars to the ON prong or ACC (whichever they name it) then run a power wire from your fuse box (I suggest the HORN fuse) to the OFF or POWER prong. (I say on and off because that is the side of the switch they should be on)

Do you already have lights under the dash? Those show better and are easier to hide the wires as well...

My blue led tubes under the dash.

Under the seats are only good for backseat floorboard lighting. (Got those too if you want a picture to help you decide.)
