I have a 2021 peterbilt with a paccar radio part# PP107180-7101131200, I am looking for a factory harness to install an amp and sirus radio. Do you know of any such thing?

If you bought our BT ISOI DIN and the BT ISO DIN F these 2 together will give you a way to splice a preamp adaptor into the factory radios wiring
