All in all it wasn’t a complicated install. You can’t mess up the connections. You do have to pull some panels and piping off to access the areas needed. Only question is if you have a fuel controller as well, does the throttle position sensor plug matter as to which unit receives the signal first? Is there any compatibility issues if I use a fuel controller with this ignition module? Nothing is stated in the instructions but the atv starts right up and seems to idle better already. Now for a good long day ride to test it out.....
