Review on 🔊 Enhance Your Mobile Audio Power with 500Amp Continuous Battery Relay Isolator: Uninterrupted Performance by James Roberts

Installs on Jeep JL between the battery and fender on the existing screw on the ground wire block. I had to bend the bracket slightly and sand the plastic on the wing. I used 2ga. 400 amp fused wire (Mega/AMG 400 298 series) from battery to relay and on/off by cab auxiliary switch. The 10,000lb. Warn winch is rated for a maximum load of approximately 360 amps. The relay gets a little warm, but so far so good. It's quite big. I tested this by towing my truck (about 7500 pounds double cab GM 2500) up my street. I even had a couple of 2x4s on the way to bring it "alive" with a full spool of cable. About 100 feet. Then back to real life, pulling the highly centered 4runner off the rocks in the mountains twice.
