This wiring adapter converts the two-connector factory stereo wiring in your Freightliner truck to the new standard ISO-DIN plug. After plugging in the PP201491 adapter you will be able to directly connect to any DEA355, DEA5XX, or DEA7XX series stereo. This includes all late model Delphi and all current model Aptiv brand heavy-duty truck stereos found on the STS website.
If you are going to install an aftermarket stereo such as Alpine, Jensen, Kenwood, Pioneer etc.., you should use this PP201491 wiring adapter plus our PP205250 ISO-DIN to Aftermarket adapter which allows direct wiring to an aftermarket brand stereo harness without cutting into your factory wiring.
