I have a 2003 763G. I see there are plugs behind the blanks where the switches go above the door (three on either side of the parking brake). I was wondering if I installed the switches for the turn signals and four ways would they work or is there something else required? Also, is it possible to get the "bucket positioning" switch to work with minimal effort or what? It wasn't activated from the factory but I would like to have it if I could. Thanks.
