Hi All, first time posting for help, hope I’m in the right place!
I purchased a RV-9A earlier this year (first plane had to be an RV!). It came with 6 ventilation fans built into each seat, though they are not hooked up. I was provided two harnesses by the owner.
There three wires which need to be connected to the airplane for these fans to function. Red and black, which are pretty self explanatory, but each harness also has a blue wire. Each harness has a single switch and 3 different fans speeds so I imagine this blue wire has something to do with this feature. Any guidance would be greatly appreciated!![IMG_8752.jpeg IMG_8752.jpeg](https://vansairforce.net/data/attachments/47/47950-c313c89a053588b27e9375688611dbce.jpg)
