’93 toyota camry keyless entry

I have a question, I bought a keyless entry remote system(no alarm incuded, just lock/unlock) and I do not havea  wiring diagram to install it, I already have one installed, it is near the pedals and all the wires down there(near the drivers side door) where it's wired up..though it no longer works really.  My vehicle is a 1993 Toyota Camry 4 door, I need a relable Wiring diagram so I could wire all that in.

Thanks for any help.
