HEI installed not charging, need help!

From what I gather, you have a 1969 harness, which you had to cut and splice a new connector on to fit the 1970-up voltage regulator and are still using the 1969 alternator, which does not work with the 1970-up VR. Also the 1969 harness does not have the second field wire to the 1970-up alternator?
