I recently bought a product that connected into the back of my 03 non bose head unit cd changer output. It turns the cd changer output into a pair of rca jacks. To do this i must wire a yellow wire to a constant 12 volt source behind the radio and a red wire to a switched 12 volt source behind the radio. Could someone please help me out and explain to me how to do this. Thank You.

 

anyone

 

switched source could be your lighter
