Step #1- Remove the expansion chamber #2- Cut the two cable ties securing the coil to the chassis .#3- Remove the spark plug caps from the spark plugs , then remove the pto side spark plug cap from the high tension lead wire . #4- disconnect the orange and black wires that connect the coil to the cdi box . #5- remove the coil assembly , then rotate the coil 180 degrees with the high tension leads facing downward . #6- Route the high tension leads in front of the coolant hose so they are located between the coolant hose and the engine . NOTE: make sure the pto side high tension lead is routed in front of the steering post . #7- position the coil in the chassis mounting location , then secure the coil to the chassis with two cable ties . #8- connect the black and orange wires . #9- install the pto side spark plug cap onto the high tension lead , then install the spark plug caps onto the spark plugs . #10- install the expansion chamber . These are exact instructions word for word from arctic cat . I found that it did not work , through trial and error i found this way to work flawlessly , keep the high tension leads on top , rotate the coil so the writing is towards the silencer , i did this without unhooking the black and orange wires and with the pipe still on , it only takes a couple of minutes and it worked for me .
