The male connector end of my keyboard, Apple Keyboard with numerical keypad, got squeezed beyond repair.

I chopped off that bit and newly stripped the 4 leads: Red, Black, Green & White/Grey.

I'd like to solder these to a new connector.

I'm wondering:

  • Is there a "standard" for the order of USB cables globally or for Apple keyboards?

  • What's the right order in this product's case?

  • Clean down the old connector to ascertain what color wire was soldered to which pinout and put then back them back the same way it was wired to begin with. – user3439894 Jul 8 '16 at 23:10

USB pinouts are universal. So, once you have the IEEE standard used, you should be able to resolder a new connector with no problem. In this case, the USB connector used on the Apple Keyboard is a USB v1.1 connector.

I have included the pinouts for USB 1.1/2.0 below for reference.

Short of that, I am sure you could use the continuity function on a multi-meter on a USB cable to figure out which pin goes where

  • Thanks for answering. I appreciate the reference image. Can you elaborate on using a multimeter though? How could you use it to figure out the pins? – Phil Jul 9 '16 at 7:30

    It would require removing the back cover of the keyboard. In USB, it's a straight through config: pin 1 -> pin 1, pin 2 -> pin 2 and so on. You find pin 1 on the keyboard PCB, and continuity test the colored wires to find pin 1. Once you have it mapped, you can attach a new connector. – Allan Jul 9 '16 at 12:45
