this may seem to be a stupid question but i have no choice but to ask it anyway. i have an 88 GTA with the radio controls. bought the car and the horn does not work. took off the radio control pad to find out that non of the wires were hooked up. i plugged in the connector for the radio controls on the right hand side. i pushed in the wire with the spring into the steering wheel on the left where the spot is for it. then i have one more wire with a female spade connector on it.... where does it go???? i assume its a ground, i disassembled the whole thing and this particular wire just hooked up to a metal plate inside the radio controls. there is no male spade connector anywhere inside the wheel that i see... any advise would help!! maybe a pic if someone has it hooked up in there car!

 

That should go to a male spade connector on the back of the horn button.
