Radio Hack Job

Whoever had the car before me... wow. Hacked the wires all up, there is barley any wire left at all. I managed to strip all of them, and I worked at a garage so I got the wiring diagrams for the radio (which is the one with the built in amp, don't know what that system is called), but I can't get my hands in there to attach the really, really small wires to the harness of my headunit. Does a wire connector/crimp exist where I can just slide the two ends of the wires in and press a button or something so they are togethor? That's all I really have room for, and there is no way I am going to take everything apart and rewire another car (my last car it was necessary).

No one knows an easy connector I can buy for connecting 2 really small wires?

Well if they have those type of connectors at autozone, I may have to take a trip there. Thanks for the tip I would fix the wires permanently or rewire the whole thing, but my last car (truck actually) was a jeep cherokee that I built, and one of the things I did was rewire the whole car with crossovers, amps, the whole works. I never want to do that again, and I'd rather fix a connection that breaks than rewire the whole car.
