DIY home SOG system for your van - at a fraction of the cost

The SOG System works on the basis of adding a little bit of oxygen into the cassette and venting, it out through the door where the cassette is accessible.
This DIY system costs around $20 and uses the vent system in the existing cassette to vent without drilling holes.
no need to drill holes through the doors or hook and unhooked as you empty the cassette

Where is the flush tank located?

I’ve done a very similar thing with mine. I triggered the fan from the flush solenoid with a timer that keeps the fan running for 15-20 mins. Works great BUT you need to have a seal (I used sticky back foam) on the port that mates to the cassette. Without that the air won’t pull through cassette it get sucked in through the gap.

Any chance you detail how you mounted the switch?
