Gen3 Engine On Sensor Cable

This optional cable changes the threshold for connecting/disconnecting the batteries in the Jeep Wrangler JL & Gladiator due to its smart alternator. 

Not needed for vehicles with alternators that do NOT drop the voltage down below 12.7v while the engine is running, such as the Toyota vehicles that we support, or the older Jeep JK.

This item is compatible with all Gen 3 dual battery systems. 

For installation instructions, watch the video for installing the Gen 3 dual battery system in your vehicle on our Support page.
