Very new rider

I went out for my very first bike ride on a 92 tw 200 today. (actually first bike ride on a dirt bike) So being so inexperienced I did end up crashing. I went the whole day without a hiccup and when I tried climbing a small steep hill that the trucks tailgate was layed on I grabbed a little too much gas while trying to put the front brake on and ended up attacking an unsuspecting barbed wire fence. No worries I suffered only a 6" cut to my forearm. I felt more stupid than anything, LOL. In the process I managed to sever an electrical cable that comes off the clutch handle. I'm just curious as to what this electrical cable is for? The bike seems to work just fine and right now it is too cold to go out and trace the wires. It's probably a stupid question but being new to bikes and TW's I probably will ask a lot of them. Thanks, SMitty
