Which wire is the high speed? Brown with yellow stripe or brown with orange stripe?

I could guess and say brown/orange was how mine was, but can`t you just shoot 12v to each wire and see? :confused:

I could if the truck wasn't so far away from me. I have my DC Control unit hooked up to the orange one, but wasn't sure if i had the right one because I was in a rush hooking it up and just guessed.

I THINK its the yellow. But since my truck is at home and Im at work I really dont know.

It's the larger guage of the two.
