I pulled my old steering wheel and attempted to replace it with a GT/Fire Arrow wheel. I'm having trouble,however, with the horn blaring constantly when I turn the key. Obviously the wiring is wrong. I'm unsure how the two push button wiring will work with the one center horn on the new wheel. There is no obvious place to use any of the old wiring, but the horn blares if I just stick on the new wheel. I'm obviously a newbie and would appreciate any help. Thanks.
