Positive coil wire

Not sure what you bought or what you are doing.
The wiring diagrams are the last pages of the electrical chapter in the service manual.
Pretty much everything is essential except maybe hood mounted turn signal or something like that.
There was a change in '69 to the neutral safety and reverse lamp harness (transmission).

Basic power schematic for '69

Power is supplied to the welded junction (solid black circle) from either the battery or the alternator.
At the junction there are 3 feeds. One to the key switch, One to the always hot fuses, one to the headlight switch.

The regulator you bought is for an isolated field alternator. Those came standard begining in 1970. If you ordered your harness modified for that, then the regulator is correct. If you ordered a factory replica harness, then a regulator for a grounded field alternator is needed.


For MSD see the original Autotronics info I've posted here

For magnetic pickup distributor, don't use the white wire. Connect the purple and green pair to the distributor pickup wires.
