The PP201746 is the ISO-DIN radio plug used in most semis and equipment built after 2005. It mates with the DEA500 and DEA7xx head units, and with the older Delphi radios that use the same connector.
Use it to put the factory plug back in the cab where a previous stereo job cut or rewired the harness. On an older truck or other heavy equipment, it converts the existing wiring to this ISO-DIN plug so a current Aptiv radio will connect. It also works for a custom install in a passenger vehicle or any other 12-volt application. The loose ends have to be spliced to the vehicle. There is no plug on the truck side.
