Ken, you'd have to add at least an MSD cdi box to run their rev controls. I have 2 sets of MSD 6 BTM's, which are boost retards and ignition boxes for blower motors and 2 rev controls, although I think these BTMs take the little plug in chip that limits revs. I'll look. The setups are already wired into a Mercury harness. This stuff is all only about 10 minutes from you.
