2006 Peterbilt 378/379. Truck came with two speakers. Adding two rear speakers and need to know what pins go in the truck side plug to add wiring.

The easiest way is to purchase one of our BT ISO DIN and a BT ISO DIN F harnesses to create a set od connectors that will plug between the truck connectors and the radio connector where you can ID and make your extra connections for the rear speakers.  This way you are not cutting or splicing any of the factory connectors and wiring.
