Hey all, so I bought a new double din nav Unit for 2004 suburban LT with existing double din factory radio. But I'm having trouble finding a harness adapter/interface that fits the existing harness. It's a 24 pin harness but the interfaces pins don't line up with the existing harness pins. i.e, power lines up with speaker vice the connecting power wire..... anyone know of a harness that is a legit fit...
Or can I simply ignore the wire colors and attach the new radios wires to the old harness wires by attaching them to the right pin stall.

Thanks.
