This was purchased brand new, but as you can see it's been in my toolbox for years. The box shows wearing but the product has never been used or installed. Comes with manual and the pigtail and the original box.
I purchased this for my 1991 Mitsubishi eclipse GSX before AEM v1 was an option back when DSMlink/Eprom flashing was the only option.
Selling this for someone who bought a JDM import and needs a brand new replacement or someone who wants to just flex a piece of HKS history on there JDM mitsu. 
Should work with all Mitsubishis older Mitsubishi's  4g63 4g64 4g63t 6G72 6G72TT 6A13 6A13T

The entire manual is in Japanese so you can use the google lens / google translate camera app to convert to your language of choice.
