I have wired up all the front + rear speakers, grounded the black wire. I just dont know where to wire up the yellow wire(battery) and the red wire(ignition) inside the car. If i wire the red and yellow together and connect straight to the battery the headunit works fine. Anyone know where they are located?

thanks in advance

just add a line to the battery and another to something that comes on when u turn the car on, e.g cig lighter.
