Ignition trouble shooting

Did the electrics work before you dropped the 440 in?

Unfortunately there is no later model shop manuals I know of to download. The wiring about 73 or so starts to change, and 74/5 is much different. You can go to MyMopar and download simplified diagrams which are not very complete:

I do have a '76 manual, (paper) might be able to post some of the wiring, but the way the later stuff is drawn, it's more difficult.

If you can show a photo or more closely describe the wayward wiring, I might be able to steer you
