My ATC unit cooked several years ago, so I have been using a wire and hemostat switch, LOL!!
New unit and two wire harnesses were spot on! Splice three wires and two plugs and i'm back in business. The unit has been improved with more prong surface area for better cooling. GREAT value considering the dealer quoted $300.
Does it work, yes. Like original, no. It is an entirely different design which is fine but absolutely zero instructions on how to fit new in place of old. I myself am mechanically inclined and it still took me several minutes to figure out correct fitment.
