Black tar (dialectric) 67 coupe

Can anyone tell me about what the black tar like substance that was sprayed into the connection side of the engine harnesses? I purchased the cables from classic industries. I assume this is some sort of weather insulating spray, however, the metal connector ends are completely covered with this stuff. I can't believe there wouldn't be connection issues leaving the sticky matter applied. Mineral spirits seems to desolve it, but wanted to be sure I was doing the right thing. Any input?

It is just black urethane sealer. It's the same stuff used to seal the windshield and back glass. Also used around just about all major firewall penetrations. It stays soft and gummy forever. Just stuff it in the backs of the sockets, and put a couple "ropes" around the inerior side of the connector to keep water out.
