Automotive Electrical Connectors,while doing various wiring tasks on my cars and in particular, while rewiring my 1975 Suburban, I 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 wires), what they look like complete with dimensions (for easy visual ID).
Feature introduction :
Automotive Electrical Connectors available for 10 through 22 gauge wire
10 gauge is a really tight fit, 12 gauge may be a more realistic limit
1/4" blade terminal design.
Most common style I have ever seen - GM, Chrysler, and even some Fords use these
Many switches and other electrical parts use a 1/4" wide blade for electrical connections
Most common "quick disconnect" terminals use a 1/4" wide blade that will connect with these in a pinch
Connector bodies commonly available in 1, 2, 3, 4, 6, and even 8 cavity configurations
Pushes in from back of connector
To remove female terminal, depress small tang with a small flat tool inserted from the front of the connector and push out
To remove male terminal, compress the open slot in the tang with a small pair of pliers and push out
