90 xj not charging?

I finally got my xj running after a year or so and now the alt light is on. Battery charges fine with a charger. Anyone have a wiring diagram to the starter relay for it? I have generic diagrams but no color codes for the wires.
A color pic would be awesome too if available. I need to ensure they were hooked up properly.
