I added LEDs into my foot-wells.
1. I connected both Leds together.+ to +, - to -.
2. I found the yellow wire with a white stripe in my passenger foot-well.
3. I added a splicer connector to that wire.
4. I ran a wire from + side of the LEds to the splicer connector.
5. I added a ground wire to the - side and grounded it to the tub bolt by the harness in the foot-well.
If you want them to also work on a switch you need to find or run a hot wire. Splice into the hotwire and run it to the + side of your Leds with switch in between to you turn on the flow of power.
