Am I the first one to get one of these and try on a 7? I am about to install it with my TII leading coil...the wires are almost identical excpet for two. The only question I have is ...when installign an MSD amp do you guys set it to four cylinder? If not what do you do? When using the TII coil (That just came literaly 4 minutes after I posted) Do you guys use just the plastic coil it self or do you also conserve the the botom metal portion as well?
