Good morning listers ,
I wanted to install a co and smoke detector in my 1988 Westy. The detector is from Amazon :
http://www.amazon.com/exec/obidos/ASIN/B005GSFUWE/sbw/

Hard wire it off the aux: battery but am a little confused on the wiring set up.
I wanted to add a toggle switch to shut power off to the detector when the Westy is down for some time. Didn't want to run the battery down. 
My thought process is :
From battery, Red wire to +, then to fuse, then to toggle switch, then to detector.
Black - to ground. Will the toggle work and save the battery in this configuration?
Thanks for any suggestions
