    i got the Zex Kit for my 2010. First question is, do I need to get the Zex spark plugs? Their website recommends them because they are one step colder than stock. Question two has to do with the MSD Digital Window Switch. I've read that I need to get the tach signal from the negative side of one of the injectors. Has anyone installed one of these and if so, is that where you got your tach signal?

    tach signal does come from injector ground. The way the ford system works to interrupt injector pulses is through breaking the ground. With the key on the power wire going to the injector will always be hot. Not sure on the plugs but you do need a colder plug for nitrous. Anything over 75hp anyways.
