removing wiring

im getting my valiant painted. im almost done removing the engine harness, but ran into a snag. the plug thats on the firewall (not the bulkhead plugs) has one or two wires coming from it going into the interior. i assumed i could disconnect the wiring on the inside and pull it through to the engine bay, but one of the plugs thats attached inside wont fit through the 1 inch hole. the only other way i can see to do this is by disconnecting the single wires from the harness plug. i tried wiggling it out with no luck. who knows how to remove wires from the harness plug?? any other ways to get this out???


thanks for the help jason
