Ever since I installed my original steering wheel, my battery drains completely. The only thing I could think of was when I did this, there was a single loose black wire running up near the steering wheel itself. I taped the wire off in case it was hot. Now the only function I could think this wire would have is for the horn button. Am I wrong? And if it is for the horn, if I ground it the horn should sound, right? That is if the horn in my car is still there. I haven't even checked that yet. Thanks for all the help guys!
