Bill : Mine is actually at our place in Colorado, but I "borrowed" these pictures to show you. The power is the Yellow with black stripe, and the light is the "standard blue with red stripe. The key here is that the twin plug has two different sized bullet connectors. I can't measure mine right now, but I assume (?) that the smaller bullet is the "universal/GM" size bullet, and the larger is the standard Ford, larger, type. Also note that the power wire is of heavier gauge.
Hope this helps,
Bob
