Ok, I thought the questions where over but unfortunately they're not. I looked up the back up alarm kit and there is not a switch available to purchase in the kit, so I am assuming it is already on the tractor. I found the actual instructions for my tractor and all it has is wires attaching to each other, so I guess I'm going to have to get the wire that plugs in to it. There is a ground wire coming out so I assume the other is a 12V. Here is the diagram for the kit.

1 R230565 Bracket 1
2 LVA11758 Audible Warning Alarm 1
3 ...... Elec. Connector Housing 1 REVERSE SIGNAL
4 ...... Electrical Connector Assy 1
5 ...... Elec. Connector Accessory 1 GROUND
6 RE227384 Wiring Harness 1
7 LVB25728 Field Installation Kit 1 COMPLETE GOODS
I just need help figuring out which parts would help me out. I'm thinking all I'll need is 3-6, is that what you all think. Thanks for helping me with this guys, I don't know very much about electrics in tractors and stuff.
