You can find the wire harnesses (plugs) for your car or truck from most places that sell car stereos. Most auto parts stores like PepBoys, AutoZone, Advanced Auto parts will have them. You can also find them at large retail stores that have automotive departments like WalMart, Best Buy, and Sam's Club. They're car and truck specific, so you just need to find the wire harness that matches your vehicle.
