NewZed, I appreciate the advice. I'll see if I can return the MSD unit. If not, knowing that I need to use the magnetic pickup install is VERY good to know. Thank you!

I have a 1974 260z that has no spark. While I don't know where the problem is, I thought it would be most reliable to swap out the Hitachi Transistor Ignition (E12-05K, single distributor pick-up) for a MSD Street Fire Ignition (PN5520) box. I called MSD and they hung up immediately after I told them what I was trying to do. So, I'm assuming I need to disconnect the Hitachi ignition box and take the ceramic resistor out of the circuit and just wire it as if I replaced points with a solid state distributor pick (diagram attached). Does this sound correct?
