how to give a JK an ignition beep like old cars had?

Hey guys!

I disabled the "beeping" that the jeep has when you leave your lights on, startup the jeep, etc etc.

However, I want it to make a constant noise like old muscle cars made.. They had a very robot like almost electronic horn sound to them. for example, my uncle's 85 mustang gt goes "mmmmmmmmmmmmmmmmmm" for a good five seconds when you turn the key to iginition.. any ideas on how the hell to get this in my jk? I don't even know what the hell to look up. lol

Mustangs are pony cars. That sound you heard was the fuel pump i think. Just put in a cd with what ever sound you like.

Just reprogram the ECU-simple

You Ign. key doesn't actually "excite" any high current circuits, all it does is notify the computer (Millivolt) that the human is ready to initiate combustion and then after several seconds (checklist) the computer will authorize ignition-


Like the doc says--just getta muscle car CD !

With my exhaust, I don't need any more assurance that the 3.8L is "on line"-
