    Any of you early "A" Body guys pull the engine compartment side of the bulkhead connector loose? Thanks

    I have mine completely out right now. Its a good idea to check the connections because as they get older they corrode.

    You want to get the plastic separated from the bulkhead housing?

    There are usually a lock clip, top and bottom, slide a small blade screwdriver in the locked area and pull on the connector. It should start to come loose. They can also be a total PIA to get apart after 50 years of sitting/corrosion.

    If you are talking about the actual male terminals, I think we covered that.

    Here's a pic I find on the interweb. You can see the "ears" sticking upward on the 3 connectors.

    Like crackedback said, use a small screwdriver to "gently" pry the tabs from the bulkhead. After 50 years they can become brittle and break...or they can bend and not return!

    Search around the boards for more info on cleaning them up and using dielectric when putting it back together.

    Well Im a little late getting pics up of my bulk head connector but we had this giant snow storm stop by and reck the weekend!!
    Here are some pics of both male and female side of the connector. Hope these give you the information you are looking for. Also take note to the one wire terminal on the front plug that is corroded. The start of what could have been a serious problem.

      All those terminals come out of the connector bodies, and can be replaced. They are callled "Packard 56" terminals and are available several places including Ebay. Be sure you get the correct ones. I got mine at "clips and fasteners."

      http://www.clipsandfasteners.com/Packard_56_Series_Male_16_14_Gauge_Terminals_GM_p/w31c030.htm

      The female ones are the ones you have a problem with. you want the ones where the sides curl around like these:

      There's a little clip on the back, insert a tiny screwdriver in from the wire side and release the clip. The male ones are sometimes harder to release. The right end of the "J" shaped part is what you release on them by pushing in from the SPADE side

        The early A's are simpler and varied more. They have 2 connectors, not the 3 when they moved the wiper motor to the engine bay (1966?). 1965 is best since it has dedicated lugs for the large ALT and BAT wires, instead of running them thru regular 56 terminals as in all other years except 1963. Those big wires tend to melt the plastic as they age and corrode, sometimes even dropping down to touch something they shouldn't (like IGN). I put a 65 bulkhead in my 64 to get that. 1963 had one regular connector and one half-width.

          BillGrissom can you post a picture of the "dedicated lugs" for the main power wires that you mentioned? Sounds like just the fix for this long time problem for other years of Chrysler products...

            I have several times. Search (from google is best). Can only work for 1964, not for later cars that had 3 connectors (I'm not sure about 1966). They can do similar by doing the "fleet bypass", which is much discussed here.

            I am guessing they dropped the lugs in 1964 to save money or such, found they needed them so put back in 1965 (bulkhead hole is 1/8" taller). Then the budget weenies noticed the extra cost, saw most failures were after the warranty period so dropped them. That is why America is so successful, with all these CEO's and MBA's cutting costs and corners so everyone buys more stuff that fails faster, but I'm just speculating.

            I did the fleet bypass on mine and not a moment too soon. The amp gauge wiring through the bulkhead connectors had just started to melt!!!

            While I was at it, I cleaned up the other terminals and added dielectric grease before reconnecting the bulkhead connectors. On my list is replacing the Packard 56 terminals...already have the terminals, just need to make time!

            I was wondering after looking at this, what size are on the 12 gauge wires going through the bulkhead connector?
