You can remove it or utilize a switchable harness. One end goes into the OBDII port and the other end has the RANGE MODULE plugged into it. In between is a simple rocker switch. The one I bought is 24" long which allows for the module to be placed under the dash or near the console.

I left mine (#RA003G, V8.6R1) plugged in all the time, but my C7 Z06 was always on a BATTERY TENDER PLUS when the car was stored. Removing it over and over risks bending a pin.
