To prevent electrical damage always disconnect the battery before doing any work on electrics.
For that you will have to remove the seat to gain access to the battery cables. Remove the negative ground wire first, then the positive. Make certain they cannot bend back and touch the battery. I have wrapped them with a rag to be safe.
If your switch is mounted on the frame, there is a lock ring that pinches the switch to the bracket. Turn that counter clockwise, slip the switch out of the bracket and carefully remove the wires paying attention to the color coding. (If the wires do not have a quick disconnect, you will have to cut them and splice the new switch wires. I recommend twisting the wires and sealing with heat shrink tubing.) Slip the switch into the bracket and fasten it using the lock ring by turning it clockwise. There are wrenches made for that lock ring but if you don't have one, try putting a rag in the jaws of pliers and turn it that way. Now reconnect the battery with the positive cable first, then the negative. Test the new switch to make sure everything works. If OK, install the seat. Always pull up on the front of the seat to be certain it is seated in the bracket. If the seat is secured, you are ready to ride.
If your switch is mounted in the housing on the gas tank it is a bit more complicated but not terribly hard.
With the battery disconnected, remove the nut at the center of the instrument housing. That's the one between the switch and the speedometer. Lift the housing and remove the screws that pinch the switch to the housing. Have a second person help by holding the housing or lay a towel on the tank to prevent scratches. Disconnect the wires from the switch and connect the wires of the new switch. Pay attention to color coding. Install the new switch in the housing using the screws. Slide the housing back into position over the gas tank and install the hex nut. Now reconnect the battery with the positive cable first, then the negative. Test the new switch to make sure everything works. If OK, install the seat. Always pull up on the front of the seat to be certain it is seated in the bracket. If the seat is secured, you are ready to ride.
