If you installed and after market radio and not a factory replacement,the aftermarket is not equipped for dimming,that is the wires to the left on the factory radio.

The thing that has me baffled is the second connector 2 blue wires which are used to turn on an amp and another used for a possible power ant. along with 2 rca jacks.. The jacks stumped me. what could that second connector use rca jacks for.. I didn't notice any power amps in the rear on the car

this is the connector i purchased instead of cutting the wires. I guess this could explain some of my confusion.
