MSD Ignition set up?

[91ka_240]

If anybody knows how to hook up a MSD Igniton Box, tell me if this is right. you got the heavy red for positive battery, heavy black for negative battery, orange wire to after market blaster 2 coil and smaller black to neg side of coil. the question is here is that i want to take the white wire and connect it to the old stock ignition power wire that went to the stock coil. and the small red wire i want to have it tied into the igntion key but i can't find a wire that i can tie it into. so i was just thinking putting a switch from the battery to it. so if any1's done this tell me what u ran your little red wire to and what your white wire to. thanks
