Works With:1980-1991
Weight:3.0 lb

This is our basic entry-level auxiliary battery installation kit for those on a tighter budget, and those with minimal power needs. Read more in the 'Power Needs' tab.

Fits: All 1980-83 Aircooled Westfalia full campers (NOT diesel) and all 1980-91 NON-camper (MultiVan, Weekender, Carat & 7 Passenger w/o sink, stove, fridge system) Vanagons.

For the following battery types: Flooded, Sealed Lead-Acid (SLA), and Absorbed Glass Mat (AGM) batteries. Not recommended for use with Lithium Iron Phosphate (LiFePo4) batteries.

This easy to install kit includes wiring, battery isolator solenoid, 50A circuit 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 (to be 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: If you also need a battery, please see our SLA1161, or purchase our Auxiliary Battery Bundle to save a couple bucks.

*If you prefer to buy the latest technology we offer, pick up a GW-LIFEPO Lithium Iron Phosphate battery, a Renogy DC-DC Charger, and our Installation Kit. Or, save a few bucks by picking up our Deluxe Auxiliary Battery Bundle.
*1980-83 Westy Owners: This kit will not power your refrigerator off the auxiliary battery, as there is no simple way to do so. This kit merely allows a 2nd battery to be installed, charged and isolated from the main battery when the ignition is off. It is up to you to wire all accessories to it.

*Diesel Owners: If you do not have a fridge relay under the driver's seat this is the kit for you. If you have the relay, you want to buy the AUX-700.

A Note on Engine Conversions: This kit is intended for Vanagons with Waterboxer engines, but can be used with conversions. However, our instructions do not cover installation on converted vans, so you'll need to be extra careful with the wiring.
