This is a tachometer that simply plugs into the OBD port. I made a mistake in confirming compatibility and couldn't use it, so I'm selling it. I was planning to install it, so I opened the package and partially applied the sponge to the cover. You can check compatibility on the manufacturer's website, so please confirm it yourself. https://shop.pivotjp.com/got.html - Brand: Pivot - Model: RPM x1000 - Color: Black - Shape: Round Thank you for looking.
