Greenstar coverage switch

I'm looking at doing more documentation and currently switching colouring/shading on and leaving it running which is leaving lots of overlaps on the headlands.

So as above I'm after ideas suggestions please of a suitable switch maybe where people have placed there's, it's to go on a red tractor hence the need for a switch.

I've thought about mounting something on the side console or having a foot pedal on the floor somewhere, any help much appreciated Lee!
