74 Dart 360 Sport

So I got out last night stripped the last of interlock I got wipers going. Wired the starter relay and the Ma Mopar ignition. The key in run ignition has 12 volts, start ignition 12 volts and ACC 12 volts. Brakes work I have the same passenger side tail light dead that's the old harness/socket I will trace and find that! Even checked the starter and it fires as well I didnt have 12 volts on the HEI pigtail I think I have to change the wire I choose from fusebox. I thought the Coil wire would suffice but I can always move it if need be.
