If you are using a lockup converter without them EMC you will need the switch. This place sell them for $70.00 bucks, however its a automatic switch and you dont have to worry about the toggle switch flipping it on/off. There are some cheapers switches around but here is the one i'm buying. For others check out summitracing or jegs. Hope this help!
