On the switching, with my multiplier I put the box near the control handle. The control hand is one that came with the factory setup. This way I can easily switch with my right hand and also switch on both. the thing I didn't like about the kit was no mention of switching power to the unit. The way my kit came was a fuse in line and connections to live power. Well with this you would be leaving continuous current to the switch and you'd have to remember to put the switch in neutral or else suffer a risk of solenoid burn out or drained battery. On my 4400, older compact tractor the fuse block did not show a switchable fuse outlet, There was an accessory, had no fuse but the power in was continuous. I can't seem to figure out where this goes. There was a red wire dingling out of the left side near the fuse block that was switchable but the voltage read 11 instead of 12 which I thought was odd. Therefore I went directly to the switch and teed off a white wire that guide said went to cruise control which I don't have. It was switchable so I came off it, adding a 15A fuse down under mat and over to the switch. That works fine and I don't have to think of turning off the control switch. But anyway the unit and other details is fine and I know Summit is coming out with items for all usages and installs...
