Thor ACE 27.1 Forward Fan Installation
I added a fan to the forward vent on our 27.1 ACE. I was concerned I would have to pull power from a nearby light but I was surprised to find the vent was pre-wired for a fan so installing the after-market fan was a lot easier than I had expected. "Tampering with the rooftop seal is not necessary."
I used a Heng's Industries Vortex II upgrade kit, which has three forward and two reverse speeds. All I had to do was remove the crank knob and then the screen. Then i installed the new fan after connecting the fan wires to those hidden provided wires of the ACE coach.
