Components for this project:
About 20ft gauge hookup wire
Several 18 gauge male and female crimp on quick connects
18 gauge wire tap-in connectors
Scion OEM style rocker switch
2 pcs flexible grill led strips
15amp automotive fuses
Add-a-circuit fuse box tap-in
Step 1: Do great prep works before the day of the installation
A diagram I sketched out that shows all the connections and how everything will be laid out show in blow image.
As you can see in the diagram, the led strip on the passenger side connect to the extra wire length and then get tapped into the led strip on the driver side, then the driver side LED strip gets connected to the extra wire length that goes through the firewall and inside the car under the steering wheel above the pedals. Then a ground wire is tapped-in into that same extra wire length on the - side and gets grounded to a bolt. Next the – and + ends of that same wire goes through the firewall, in the car and goes to the switch, and finally the fuse box tap-in goes from the switch to the fuse box underneath the pedals.
