Snapper s50x headlight installation

Gentlemen, I have a set of headlights for my S50X ztm, It states in the instructions to plug in the existing wires to the new light switch, now my problem is I can't find the orange and black wires that are supposed to be pre-installed from the factory.

I have looked everywhere, I even opened up the wiring harness and there are no extra wires in there.............Help!
