What you'll need:
1 - car adaptor for your GPS
2 - some thin gage wires, 2 colors preferred
3 - electrical tape & cutters
4 - some zip ties
Step 1: Tapping into the lighter
*** BE SURE car is in OFF position ***
Once you open up the bottom, note the color wiring of the lighter.
Disconnect & open the wiring terminals by pressing the locking plastic tab & pull. Then connect your wiring there.
I used double strand, just incase of overloading.
