I flat tow (all wheels down) my 2006 Mini Cooper S behind a motor home. I realize other cars may be better toads, but being able to drive a mini when I get to my destination is worth it.

When flat towing any vehicle the front wheels must be able to turn. Thus, the ignition key must be left on at least to the first aux position. Leaving it on for an extended period drains the battery. I currently disconnect the positive battery terminal.



My question is:

Can I add a switch to just disconnect the ignition circuit and keep power on to the rest of the car?

 

It seems if you pull fuse FL7 (50 amp fuse) in fuse holder 3, it will remove power from the ignition switch. It also will remove power supply to the fuse panel in the driver footwell. Actually, quite a bit goes through that circuit, so even installing a switch would have the same effect.

 

thanks
