There is no way you had it wired correctly if you had mud on either an Evo 6 or 7. Those pickups are straight up "icepick in the forhead" clarity with a side of "Sweet Jesu - the output." I've owned a lot of both the 6 and 7 versions, and I am a freak for clarity, especially on 7's.
Black and White get soldered together, red is your hot, green and bare go to your grounds, is usually what I go with. (Obviously you can get creative on which sides of the coils get joined, but if you stay consistant, it is usually safer.)
