[QUOTE="jsloan10, post: 928051, member: 560397"] Alright listen up. You need 2 power sources, one is a constant power wire that is on at all times, the other is a switched ignition wire that is only on when the key is turned. You can use a simple curcuit tester to find these (the needle with the light in it and a ground lead) Ground the tester first, touch the tip to the suspected constant power lead, when you find the wire that has power when the cars shut off the tester will light up, you've found the constant power. Now touch the tip to the next suspected power wire and turn the ignition on and off, if the test light turns on and off with the ignition you have found the switched ignition wire. The switched ignition wire provides the main power for the HU and all its funtions. The constant power wire maintains the HU's memory when the car is shut off. They both need to be connected in order for the HU to work. If this is confusing to you then you need to talk to somone in the real world to help you do it in person, and Google'ing up some info to teach you the basics of wiring prolly wouldn't hurt.
