What is the correct wiring information to a 1994 chevy suburben manufacturer stereo?

My husband isnt sure about the wiring since hes never installed a stereo to an older model car.I need to know what all the wires mean|||http://www.installdr.com/InstallDocs/GM/鈥?/a>|||havnt got a clue thats what the internet is for- good luck|||Here ya go.http://www.the12volt.com/installbay/ster鈥?/a> But I would recomend just getting the adapter plug for your unit and vehicle. Saves cutting wires. Good luck
