ES Electronic Specialties 149 Universal Test Connector Kit, 54 Piece

Only one teeeeeny dislike and that's with the size of the set. I won't ever need about half of the set. But what I do use I use all the time and they're perfect. The pin and socket sizes are dead on. I had made up 4mm banana jack test leads from an old pair of fluke cables pror to receiving this set and all the jumpers are nice and consistent when using then on the MM leads. No more trying to hold a test lead in a 4 mm hole and get a good accurate reading. Having 2 of each side rocks cause you can then pair them with male to male 4mm jumper and make true jumper wires to bypass circuits, test cable and circuit ressistence etc. Definitely a must have in the truck/automotive world.

A lot of variety, it's had everything I've needed so far as a transport truck mechanic. Decent case. Mild complaint is the terminal end is a little thick which makes it a little tight on the smaller connectors but it doesn't cause any real issues.

I have used these a good number of times and they have all the pins that I need. I work at a Ford dealer and these allow me to diagnosis electrical issues without messing up the pins or terminals.

These are only "ok". They do not fit inside of standard Fluke test leads. And the metal is weak. I have broken a couple male probes just simply bending them while probing terminals.

As a professional mechanic you often are probing connectors to test wiring. This kit has everything you need, other than a dmm, to test any and every connecter out there without damaging the terminals. Its vastly cheaper than the GM official kit and contains more connectors.

I really like this little kit, it has a good assortment on terminal sizes. The only downside it the rubber around the terminal is a little big so if your testing a small connector it may get a little tight.

I ordered this kit for my husband who needed it at work. He is very pleased with it, uses it often and was especially pleased that this kit is identical to his coworker’s who paid a lot more money for his from a tool truck.
