Model SF3-RUSB
Dual 12 volt 2.1 Amp USB Socket
Steps needed to install your 12 volt power station
1.- Remove the LOWER left grab bar bolt. When the bolt is removed there is the metal recessed
washer, be sure to keep that in place. Then take the new Bolt and spacer with the lower mount ball
and bolt to lower bar arm of the grab bar mount. Do not tighten down until the Power Socket is
positioned like the picture below. Too remember this is fully adjustable so final adjustment can be
made based on the desired position.
2.- Take the USB Power unit assembly and attach to the lower ball mount you just installed. As you
see now you can adjust the unit to any desired position.
2.-The USB power unit comes two options for power depending
your F3 model. If you have an F3 without the rear trunk meaning not a Limited model, under the rear
passenger seat is a rubber boot with a factory fused accessory wire. You can plug the unit into the
accessory wires in that boot shown in photo below. Be sure the red plugs into the positive marked
wire and the black to negative.
