I dont have any close ups but heres one of when it was on my truck.
It you have to get the wiring that goes into the cross bar and the wiring for the switch. When i got my gobi i just used the existing wiring. My gobi came with some wires and a switch and a little piaa box ill send those with it if you are interested.
