While doing various wiring tasks on my cars and in particular, while rewiring my SuburbanI have learned a lot about various wire connectors used in the automotive realm. I started this page as a personal "crib sheet" so I could keep track of what connectors and terminals were used in what places and to cross-reference the names I found to something I already knew.
As it grew, I decided to create a page describing the various connectors, the common names for each style connector, how they come apart for adding and replacing wireswhat they look like complete with dimensions for easy visual ID. This is a copy of an old manual page oddly enough, I think it's for a Packard that shows some of these terminals and how they work. Here is a picture of a typical mid's GM bulkhead connector from one of my website readers that shows how the Twin Lock terminals look when they are installed in a connector.
The grease in the connector is the remnants of the original dielectric grease that GM put there when they built the vehicle. Here's two common Ford connectors with the terminals already removed and the locking device removed and set below the connector body.

The one on the left is a weatherproof mini wedge lock style with 8 terminals but only 5 were used in the rear gasket shown above the connector bodythe one on the right is a non-weatherproof wedge lock style with 12 terminals. Whenever you run wires through a bulkhead firewall, floor, etc.
For basic grommets, Packard 56 style connectors inside of a grommet, or a nice Weather Pack style wire bulkhead disconnect, check out American Autowire. Their catalog of individual pieces instead of whole wiring harnesses can be tough to find; you have to get to the download a catalog pagethen you can select a section to get. Select the "Connectors, Terminals, and Grommets" section for the firewall grommets, and the "Bulkheads, Disconnects, Grounding, and Accessories" section for the connectors in a grommet and the firewall disconnect.
Getting the entire catalog is fun, but can take a while on slower connections, or even on faster connections. Thanks to one of my readers, Bryan Symons, for letting me know about these folks.
Non-sealed connectors used in "exposed" areas engine compartment, bulkhead connectors, etc. Note that this is different then the thermal paste you use under an HEI or ignition module or the "improves connectivity" goo you use on battery and other terminals. Dielectric grease is basically a gooey, semi-liquid insulator that prevents voltage from flowing from one place to another - it's like wrapping something in electrical tape. The thermal paste and "improves connectivity" goo are conductors - they help bridge small gaps in the terminals and provide better connectivity - it's like connecting things with a good wire.
If you slather dielectric grease into the terminal side of a connector, you may find they don't connect very well anymore unless the terminals are tight enough to push the grease out of the way when they get pushed together. On the other hand, making a trail of the "improves connectivity" goo between your battery terminals might cause unwanted special effects. Many places sell the wrong stuff - so be aware. This is super-important for the thermal paste under ignition modules, but also important for retrofitting older non-weatherproof connectors with new wiring.
Waytek Wire sells dielectric grease. Radio Shack and most PC parts stores like newegg. Most auto parts stores will sell the "improves connectivity" goo for use on battery terminals, taillight sockets, and the like.
I have a tube of each around from various projects, and when you need it, you need it. In recent years, many of the large car manufacturers have started "mixing and matching" electrical bits from different places, and different places keep getting bought and run by different parent companies.
For example, Saab was owned by GM for a while, so they use GM stuff on any newly designed components after the takeover. In some cases, you can even find GM electrical connectors in a Ford - in particular, I've been told that the MetriPak terminals are seen on and up Fords for the headlight connectors. I'm told Saab does a very good job in this regard, and since they use a lot of GM stuff, that could be useful.
Kudos to Brian Leeper for emailing me with some important information here, particularly about the degree of cross-pollination in more recent years, and in how to find details in some of the newer manuals. Thanks, Brian!

Connectors on the firewall, without wires. Wires clipped into place on the passenger compartment side of the connector. The completed connectors, as installed. Customer reviews Rated 5 out of 5 stars. Most recent reviews Most helpful reviews.Weather pack connectors started off as a Delphi product and quickly became commonplace in the automotive world.
Most wiring systems use weather pack connectors in their assembly due to their benefits when compared to standard connectors. Weather pack connectors are able to protect from dirt, corrosion, and moisture, allowing them to last longer in the demanding conditions found under the hood of your vehicle. These connectors can still fail over time and eventually need to be replaced or repaired.
This is why it is important to recognize how and when the electrical system can be damaged. At any point, the professionals at YourMechanic are always willing to help. If you have additional questions during the weather pack connector assembly, do not hesitate to Ask a Mechanic. This article will explain how to assembly weather pack connectors, whether you are building your own custom wiring harness for a performance vehicle, or you are simply replacing an old weather pack connector.
Step 1: Install the correct seal. Select the correct size seal and put it over the wire. Step 2: Strip the wiring. Use the wire stripper to set the the correct size for the wiring being used.
This is done to avoid excess exposed wiring. Step 3: Insert the terminal. The correct size terminal should be inserted into the crimp tool. The direction in which the terminal is inserted into the tool matters: one end will have two wings that will be crimped over the wire while the end that fits through the crimp tool hole will be slightly blade shaped. This is what will be installed into the connector. Step 4: Perform the crimp. With the terminal installed into the crimp tool, the wire should now be placed through the center of the terminal and should fit without much difficulty if the proper size is used.
Next, the tool handle will be compressed. This will push the ears of the terminal onto the exposed wire and form a tight connection. Remove the wiring with the terminal attached from the crimp tool and pull gently on the terminal to make sure it is secured. Step 1: Install the wiring into the connector. Be aware that there are female and male connectors. Which one you will use is determined by what job is being performed and the layout of the wiring.
The wire, terminal, and seal should all be assembled as one piece. The terminal should be installed into the back side of the connector in the corresponding slot. Push the wiring in until a click is heard. The click signifies that the barbs on the side of the terminal have hooked into the connector. Step 2: Lock the connector together.
There will usually be wires all installed into the same connector. Once all the wires that are needed are installed into the connector, the connector lock can be shut, and then the connector is ready to go. With the connector finished, it can then be reinstalled into the wiring, or you can continue building the wiring harness.
