1969 Dodge Dart - Engine Compartment Main Bulkhead Connector

A small screwdriver prying up (to the sides--top and bottom) got the three plastic connectors off. The one for the windshield wipers was particularly nasty. Sprayed with Deoxit. Thanks for your help!
If you got that far, its prob worth your time and trouble to remove the terminals and then clean them good.
Also get some new seals from Detroit Muscle Technology (DMT).

Some pictures here.
