Electronic Igntion Question

[2-66 Cudas]

About ready to fire the 318 in my Black Barracuda. Awhile back I printed out a diagram for an electronic ignition set up using a 4 terminal GM HEI module. It shows the dizzy wires going to the the W & G terminals which are different sizes. I have an orange wire and a blue wire coming out of the dizzy. Which color should go to the large terminal and which to the small?
