you will need to get a cord that connects to the sterio and then you need to match them up with these wires
the colors for the radio that are hooked up to the car are

• orange is power
• red is egnition
• blue is power antena
• black is ground

other ones will most likely be the sterio wires you just need to find colors that look a like and they will most likely match

hope this helps

DON'T REMOVE FACTRORY CONNECTORS!!!!!!!!!!!!!! Spend $15 and buy a wiring kit. It plugs right into your vechile wires and the kit tells you what wires are what. Splicing the wires will lead to headaces down the road!!!
