Backup light wire-color?

[SS66]

Does anyone happen to know the color of the positive backup light wire?

I cant see right where it goes into the housing because the P.O. used GREAT STUFF FOAM everywhere underneath as a ...ahem... fix for Wisconsin rust. So Im gonna have to tap into it from somewhere in the middle of the truck

Thanks

I'm thinkin it's green, but get a second opinion before you start cutting.
