Buddy, I read somewhere that some kits used all black wire and labeled each wire. Before you disconnect anything you should do the same and you may want to draw diagrams and make pictures also. A little extra time spent now will save much time and trouble when you put it back together.Pay close attention to the ground wires as poor grounds are a big source of trouble on fiber glass cars.
Buddy, I agree with Larry that any extra time spent marking the wires and connections now will pay off. Even if you find a schematic, the original owners may not have followed the color codes. I highly recommend besides diagrams and photos that you mark the wires with duct tape (masking tape gets knocked off too easy) and a sharpee. The difference in the green and the pale green wires may not show up on a photo.
