Engine On Sensor Cable

This is an optional feature for our Gen 3 dual battery systems. The fuse tap fits into a "Micro Fuse" slot in the fuse box.
Highly recommended for the Jeep JL & Gladiator due to its smart alternator. Not needed for the earlier Jeep JK or most Toyota vehicles.
This cable plugs into a built-in connector under the cover to sense when the engine is running
Changes the threshold for connecting/disconnecting the batteries
Ensures the Aux battery continues to charge even when a modern 'smart alternator' senses the batteries are full and turns down its output
Connects batteries together 30 seconds after engine starts, leaves them connected unless voltage drops below 11.6v with engine on, or under 13.1v for 5 minutes with engine off.

To use, lift bus bar cover and grab the small green wire, plug in sensor cable into the green bullet connector, route cable to the factory fuse box, find and remove any ignition-hot circuit fuse, insert factory fuse into fuse tap, insert fuse tap into factory fuse box.

The Jeep JK and most Toyota vehicles do not have a smart alternator that drops the voltage down below 12.7v while the engine is running, therefore it is not needed on those vehicles.
