New to the 2.3 mpc ,but historically on coyote platform (apples/orange)driver side can remained dry in comparison
to passenger side. Up to and including higher boost Pd blower builds..FWIW
Even in the mpc,(with port/di) it is gathering some "blow by" that isn't making it back into the intake track,tb,etc and all the other places not desired
Thinking of something similar tie both left and right side power together on one switch (main light) and backlight on pods on a seperate power to run 2 switches through the powerswtich. You run into any issue thus far ?
