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.
Step 2: Connect the car adaptor
Simply connect wiring, matching the wiring for center contact. Turn on car to accessory ON & check LED light.
If no light, switch contact & try again. If polarity was switch, also check the fuse both inside the adaptor & car.
DO NOT proceed until you verify electrical connections are a OK.
If all works, wrap the wiring nicely with electrical tape.
Step 3: Now tuck everything nicely away
Give ~ 6" slag, then start feeding the GPS end under the steering column.
Find some room above the steering column & tie it down with zip-lines on to any existing structure.
