All 4 fuse holders currently used in cars.
Fuse holder with 2 beds
My wires are AWG16 or 1.5mm2, good for up to 15A
Cable extension is with butt connector.
How to use:
1. Take a fuse out and plug this holder.
2. Insert the old fuse in the bottom fuse bed and it will work as before.
3. Use the top bed for your new fuse and wire provided to power your GPS, Camera etc
4. Wire will supply you with positive power signal.
5. Negative power can come directly from battery or any nut in the car.

Hint: If you install camera and have annoying lines, try to power the ground wire directly from battery the terminal.
