That's not a problem. It's just a matter of choice whether you go manual or solenoid. One thing you need to know when you wire in the solenoid. That device pulls a lot of current when activated. Once engaged it doesn't draw that much but on start up it does. Wiring will require the use of a HD solenoid switch to send power to that unit. Don't try wiring it direct to some ignition switch wire. That will not work. You could look at a wiring diagram for a '94-98 Dodge Cummins and see how the wiring is routed. It doesn't have to be very complicated, just strong enough to carry adequate power.
