I made a tool to remove the connectors from bulkhead connectors out of an old fingernail file. I ground the sides of the tip to make a narrow tongue to reach in and release the tab. Not that it matters but the file I used has a plastic handle making it easier on my hand and to hold on to. I haven't used in fifteen years to remove a connector but do occasionally file a hang nail with it. lol

Last year I added a small GM one wire alternator to my dart and the only thing I did was run a #6 wire from the alternator to the battery, along with the factory wire that feeds through the bulkhead. My ammeter still works to some extent but doesn't have the swings it did before. Best of all my lights are bright at idle.
