Yes it does. I had the fuse for our radio, fuse #34, remoted with a kit. In our case we mounted the switch below the steering wheel on the plastic facia. I struggled to make the connection to the fuse block, located under the dash above the parking brake, so I went to a car stereo shop and they made the connection for the price of a cup of coffee. Now we tow for 8, 10, or more hours without battery issues. PS, we had battery issues before the switch...oh, I forgot to mention, the kit is available from FuseMaster.
