Hello my fellow Toyota lovers.

I have a 1988 4runner and I am in the process of swapping out the rear stock speakers with an upgrade but when I took the panel off to swap the originals out, it has several connections with more that 2 wires sticking out of them. I tried to find the schematics on-line with little success. Dose anyone know which wires are the ones to use? Can I unplug everything from the speaker without losing rear light or anything like that? It seems that there are more things running off the speaker circuit and I don't want to cut the wrong wires or do the wrong thing... Let me know

Thanks!
