93 Camry, JVC head unit

workin on a JVC head unit hookup, replacing the old head unit. it had a 6-disc changer in the trunk. im confused as to how to hook up the back of the new head unit (the wiring), ive never done it before. it doesnt look like my wiring harness is going to fit at all, but it says its for toyotas 83 and up. any ideas?

ok fellas i really need some help here. im doin this for my friend. she bought a new JVC head unit, and we bypassed the wiring harness totally. We have the ground wire, continuous power wire, and the other power wire hooked up. I don't know how to figure out what wires go to what concerning the speakers though. We have tried different wires to individual speakers, but we can't get any sound at all. Anybody know what might be goin on? We're trying to get this done tonight, so a quick reply would be GREAT! thanks guys
