Hi ppl, sorry a similar post was done quite some time ago so i do apologise but a little lost/confused, im abt 2 install a car kit. simple question the power lead has 4 wires red, black, blue and yellow comimg from the main unit. now the red and blue have been wired 2gether. now only leaving 3, im assuming the yellow is 4 mute, now i thought for power u always had three wires where im now only left with 2 the red and black. is this all i need, to which wires behind the stereo do i need 2 connect these 2?
hope u understand this
many thanks
