1972 duster engine harness ECU electronic ignition

My '72 Dart doesn't have that connector. I replaced the firewall forward harnesses because I thought that they were somewhat brittle. My car was orginal not messed with harness. My opinion, put your new M&H harnesses in and forget about it. Though my car is a Dodge Dart and not a Plymouth Duster, they should be the same. Or, could your old harness have something to do with a California car?
