I have no paperwork on it anymore. My car was a JDM v.7 STI swap and it did not work on mine so it sat in a drawer for all this time. I paid like $90 for this item and it is designed to let your car idle down to cool the turbo after the key is removed. I only want a subaru owner to be able to use it for a good price. Car will have to be an original turbo model subaru. early WRX/STI for sure not sure about later models. there is some scuffing on the bottom side but it will never affect the use of it.
*revised: There is a splitter plug that I no longer have that is needed for “plug and play” or you can wire clamp it into the harness with auto part store connectors. Please research this item before buying as it is an older unit that may not be compatable with your particular car.Like I said, I only found it in a drawer recently and it is not doing me any good so i thought I would let it go for cheap so someone can get it to work in their car.
