Second battery installation kit for all 1983-91 Watercooled Westfalias. Includes wiring, battery isolator solenoid, 50A curcuit breaker, fuse holder, battery hold-down clamp, electrical connectors and instructions. This easy-to-install kit is designed to charge a second deep cycle battery (located under the drivers' seat) while the engine is running and isolate it when the ignition is off. This kit includes detailed, color instructions that allow you to rewire all existing interior accessories (such as lighting, stereo & cigarette lighter/12V outlet) to the new auxiliary power source. You can then safely run your electrical devices from the auxiliary battery without depleting the charge of your primary starting battery.
NOTE: This kit is designed to work specifically with the SLA1161 battery sold separately below.
*80-83 Aircooled Westy & 80-91 Non-Camper Vanagon Owners: Please use kit AUX-701 for your vehicle.
*Diesel Owners: If you have a fridge relay under the driver's seat this is the kit for you. If you do not have the relay, you want to buy the AUX-701.
