Sorry don't have any pics, but this is what I did. I used the vortex replacement vent fan upgrade. Mine only had one speed, what I can say is that with it running we really don't hear it with the door closed and the amount of air pulled by it was unreal. You could close the bathroom door and it felt like someone was blowing air really fast and hard over your feet from the air being pulled under the door. Anyway I looked for a wiring harness I could tie into. There are wires that run along the back but they are for the trailer lights. I ended up tying into the bathroom light. If you unscrew it, there is a black and white wire going to it, the same as on the fan. I ended up splicing in there with some wire I had left over from installing a ceiling fan in our house, they ended up being the exact same type wire. There isn't much to play with so you only get to cut the harness going to the light once. I had to extend the wires coming from the fan with the wire I had. I also ran the wires through the ceiling first and then mounted the fan, so I didn't have to stand there holding it while I mounted it to the ceiling. I then spliced in the wires to the ceiling light. The actual fan is a direct fit, I did have to move the vent adapter to the alt mounting location without the spacer. I also had to get a shorter screw that went to the vent lift, I bought a 8-32x1/2 stainless steel bolt from lowes. The bolt they give is too long and runs into the fan blade. It does cut down on the natural light in the bathroom but not too much. I would recommend installing the fan, it does help with pulling air through the camper. You can install it either in the bathroom or the one in the main portion of the camper, since there is a light right next to that one also and the vent opening is the same size. Also what size is your A/C unit, mine is the 8,000 btu unit. We ended up mounting our TV on the wall to the left of the door. Found a stud there next to the cabinet. Also we ended up getting the reflective bubble wrap and cutting it for all the doors and the two vents. You would be amazed at how much heat comes from the two vents.
