Electrical Question/Help

I am wrapping up my dual battery install on my V-10 X and I need some help.

Where can I find a +12VDC connection that is only hot when the engine is actually running. Not the ignition switch in the run position, but the engine actually running.

The thought about it is to automatically have it cut out the auxiliary battery if the engine is not running. There is an override switch that they call emergency that will tie the batteries together.

Thanks,
D.

I just used a solenoid wired to a switch.

Kit comes with a solenoid. They thought it out pretty well. You can activate the solnoid from the main or aux battery. How would you tun on the second battery solnpid if the min was dead? Wrangler recommends beng in dual battery mode only when the truck is actually running. I am thinking since I have a three way switch and understand the system I may eave it alone.

I have yet to find an engine is running signal. I could rig a relay off an oil pressure sender/switch.
