We have been sort of “fixin up” my sons 1967 ChevyII Nova and the time has come to wire it. We are cleaning up a bunch of electrical gremlins like a poorly designed trunk mounted battery, electric cooling fan, ignition and an electric fuel pump to name a few. We are running a lot of stuff off of relays and we have all of our electrical components established and mounted throughout the car. It is now time to wire it.

I would like to run as much of the control wiring as possible through the factory bulkhead connector as these are low amperage circuits for the relays. Problem is, I cant find these specific terminals. They are NOT the Packard Electric Division “56M” and “56F” terminals I am accustomed to on the 72 Nova or the 70 Chevelle we have in our stable. The bulkhead connectors are in good shape but I need the male and female wire terminals that snap into them. They are smaller than the 56 style and more similar to what I remember (I could be wrong about this) was used in the turn signal switch connector under the dash.

Anyone out there got a source?

Thanks in advance,

Steve

Steve, are they like the drawing of the "connectors" near the bottom of this page just above "RUBBER SLEEVES"? Click on the part # to get the price, even though it's not blue, it's clickable. Link to connectors.

Thanks Don! That looks like the one but I got lucky and found them elsewhere. These things are a little scarce apparently. They are called a “Packard Twin Lock” and they are not gender specific. The same terminal goes on both sides of the junction block. The last year they were used was in 1967 and after that the 56 style terminals were used. When I started looking for them I found more people trying to find them than I did parts. I found this place on about the 3rd page of a Google search and ordered what I needed from them. Don’t you just love a happy ending!

I read somewhere in my search that these connectors were very common on commercial agricultural equipment. I assume IH refers to International Harvester.

These are what came stock on your Chevy II. Yes, I know they say Packard (a lot of connectors from this time period are called "Packard" connectors). These were used universally in late 50 up to early 70s chevy vehicles, including trucks. They click into all bulkhead connectors

Napa also carries these in their "Belden" brand of electrical products.

Those are what I expected to find in my son's car Vaughn. But from what I understand and my research shows, is they didn’t start using the Packard Electronic Division (PED) "56" Style terminals you linked to until after 1967. Or not in the bulkhead connector anyway. The 67 Nova, or at least my son's came with the ones shown below. Here's the info from the place I bought them.

I have those Packard terminals in several vehicles, including two 66 pickups that I have rewired. I have replaced them in a number of 67-72 pickups also (I have gone through several boxes of them since the early 1990s on wiring jobs) - so I know that they were used both prior to 1967 and afterwords. I've used them on a few early 60s cars also.

I can't tell you why they aren't working on your Chevy II, unless some previous owner did some rewiring on your bulkhead connectors, and used something different.

My '66 Corvair uses the twin-lock connectors in the engine compartment connector as well as some of the under dash connectors.

I should have plenty left over if you need some Don. Just let me know and I will run them out to you. I had to buy a special crimper ($98.00 Ouch!) and you can borrow that too.

I saw your posting. I am currently reworking the wiring on our 73 Camaro and found these links that have several sources for the Packard 56 terminal and connectors as well as Mopar and Ford stuff. some have a minimum of 50 but at $0.17 each its cheaper than buyin 5 at the price some of these guys want.Hope it helps.

Thanks GeerHed,

It was the "Packard Twin Lock" terminals I had a hard time finding but I have plenty now.

Thanks for the links! I am always looking for a place to get this stuff and after wiring the ChevyII I need to re-stock my electrical cabinet for the next job.
