Range AFM disabler with switch extension
 

Used this for my 2ss to disable dropping down to 4 cylinders. Bought this new directly from Range technologies in June on sale for 189. Also Comes with an extension that I had tucked up underneath the streering column so you can flip it on and off with the press of a finger instead of having to disconnect it. Great condition. 150.

Random question, How does this work exactly?

It disabled the afm system. Just plug it in to the OBD port.

Sold!
