I have a 2005 peterbilt 379 concert class which wiring harness do i need and will have to splice any wires on the install?

2005 was a change over year for Freightliner. There are 2 connectors that work for that year. BT 00169 and BT ISO DIN. What I usually ask a customer with this year of truck if they have a factory sub woofer. If they do the BT ISO DIN would be the harness. It is the only harness with a trigger wire to turn on that amp. If still in doubt you can always pull radio to check. The BT 00169 will have 3 seperate connector for the trucks radio system.
