Just go to your local auto parts or stereo store an ask for a radio wiring harness to go from factory to aftermarket radio for your type of vehicle an then all you do is match the colors an plug and play...Thanks,James P.S. also if you type in Kenwood kdc 7009 owners manual you should be able to find the site for kenwood the will show you the owners manual for that unit...
