Probably the easiest place to find a good source for the light is at the headlight switch. The brown wire is for the park lights and that would work. I believe the dash lights are a light blue with red wire but I'm not positive. Take a test light and check to see what wire has power when.

You use the wire on the negative side of the coil....tan with yellow stripe.

You splice the green wire from the tach to the tan wire at the coil.
