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.
Recommend, however, mine seemed a little short once installed. Hopefully its working as advertised and recommended. Satisfied item arrived on time and without damage. Brought dual battery kit through Northridge4x4. Also received without damage and with all advertised parts and hardware. Strongly recommended for anyone wanting to get rid of AUX battery and desiring a well made battery system. IMHO, best on the market today.
I took my time and correctly installed my Gen 3 Dual Battery system in my ‘21 Mojave JT. The YouTube videos were a great help and now that pesky ATV battery is no longer a concern of mine.
Installed the Engine Sensor Cable on my Genesis Dual Battery Kit that is on my 20 Gladiator. Extremely simple plug into the control box pre-wired connector. The other end piggybacks a fuse in the fuse box (F58). Only had to make a slight modification to the fuse box cover for that wire to run out. That mod took about 1 minute at the most.
Once again Genesis has made a superior product for their fantastic Dual Battery Kit.
