My 90 Wrangler doesn't have a accessory point on the ignition switch so that I could listen to the radio without almost starting the Jeep. Is there a ignition from another Jeep model, or even another Wragnler that would fit it, that has the accessory? My Wrangler doesn't have the tilt steering wheel if that makes a difference. Its the 2.5. Will turning the key to the "on" position drain out the battery faster than if it had the accessory? I don't do it for the fear of that, since the fuel pump kicks in, and the heater controls work along with it.
