I have a very rare backboard Air Purifier for sale this unit has been tested and functions well.
This is very easy to set up there is a switch that is placed in the console.
A female plug in the fusebox connects to the wire harness that has a male plug that comes with this unit. The 'AUTO' feature works by sensors inside the air purifier.
This unit is so simple to introduce into your vehicle virtual plug n play.
Please pm if interested.
