ES Electronic Specialties 149 Universal Test Connector Kit - 54 Piece Set for Automotive, HVAC & Electrical Testing - Perfect for Mechanics, Technicians & DIY Repairs

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.
