I attempted to replace the RF HU out of my 05 Titan LE using the same wiring harness from my 05 Frointier. Everything snapped together and the stereo powered on, but I got no sound. Does that have anything to do with the 3 connectors that came out of the back of RF HU or the connector to the bezel? Do these connectors need to connect back into something? I know almost nothing about car audio, so any help you could provide would be greatly appreciated.
