There are 2 ways to set this up the first way is with a toggle switch placed any were you wish, the other way is to set it up so it goes on and off using your stop/run switch.
The first thing you will need to buy is the MAIN SWITCH STEERING part #2635545 find one that’s unusable you don’t need the key part just the wire and connector.
Next you will have to cut the wires closest to the ignition. You will see 5 wires inside, find the brown wire and get rid of it completely. Next you want to find the 2 thin wires and connect them together using solder or tape if you want.
The remaining 2 wires are what you will hook your switch up to that’s it. Put the switch were ever you want.
For the other way using the engine cutoff switch I have to look at the wire diagram again but you repeat all the same steps as above just tie up the 2 small wires together and tie the 2 big wires together and get rid of the brown wire. Then you have to go into the main harness and make a connection, let me look right now.
