9-Pin Adapter for heavy duty vehicles circa early 2000's to the present.
Note, you must have a compatible diagnostic port to use this Adapter. See the Getting Started document for more info on diagnostic ports.
If you do not have a 9-pin diagnostic port, you can use this Adapter along with a converter cable. See this link for more info on converter cables.
The Adapter comes with the latest firmware and hardware. You do not need to order the firmware update.
Important Note, the Adapter is only for 12 volt diagnostic ports. Plugging it into a 24v source will damage the Adapter resulting in an expensive repair.
