Nikon's 10 pin layout and the MC-25 adapter

Not too long ago I ran into a problem with my MC-25 cable and Pocket Wizard motor drive cable.
They both broke and I needed to splice the two together. I called Nikon 4 million times and every
camera repair shop from New York to Bora Bora. No dice. Apparently the cable is not considered a "part"
and they wouldn't give me any information on it. So I broke out the wire cutters and the volt meter and went to town. . .

On the camera:
We only know what six of the contacts are for so far. So here's what they are: Diagram of the pin layout. The "K"s are the keys. Line up accordingly.

Pin 1: Shutter
Pin 3:
+5v
Pin 4: Receive
Pin 5: Send
Pin 6: Ground
Pin 7: Ground

 The MC-25 and what those colored wires mean.

With the cable attached to the camera, and cut open to see the wires; here are the colors as they correspond to the above number diagram.

1: Red
2: Brown
3: Gray
4: Purple
5: Orange
6: Yellow
7: Green
8: Blue
9: White
10: Black

Now that we have all of that out of the way, here's what you need to do if you plan to splice a radio slave cable into the MC-25 (recommended if you can afford it, as the strength of a splice is a lot stronger then that wimpy little screw into plastic).

1: Cut off every cord except for the red, purple and yellow ones.

2: Splice the red and purple cables to one of the two in the slave cord.

3: Splice the yellow cable to the other remaining cable of the slave cord.

4: Make sure you protect the splices with a little electrical tape, as well as making sure the other seven wires are covered.

5: Lastly wrap everything up in electrical tape. I suggest making the cable into an "S" shape with the splice in the center, and then tape everything up. That way you help add strength.

Make sense? Good, I hope everything works out correctly. Happy shootin.' Questions can be sent my way.
