Ok, here is the how-to guide to making a DIY cable so the Sicce SDC 7.0 pump can be powered with Kraken.
First, you'll need to buy these:
Amazon.com
You'll only need the Female side. These are quality connectors with quality wire. Maybe you can find someone that sells only the Female? I couldn't find them, but I'm sure they are out there, I didn't spend a whole lot of time looking. The first ones I bought were advertised as 18AWG wire, but when I got them, they weren't. The wire was super tiny and thin and defintely not 18AWG, so be careful. From what I have read, the guage of the wire DOES matter.
Next, you'll need one of these for each DIY conector:

These screws are tiny. If you can solder and have the tools, you can get the solder type. I don't, so I went with the screws. I cannnot even see the screw tips they are so small, and if your screw them out too far, they can fall out, and trust me, they are so tiny, once one hits the floor, you will never find it
When you open the Sicce connector going into the controller, you will see:
Red wire connected to pin 1
Blue wire connected to pin 2
Black & White wires connected to pin 3
Nothing connected to pin 4
Below is the pinout for the Kraken.

Now it's time to make the connector.
Here is the wire before assembly. I used a heat shrink tube (probably not necessary). Put the tube on the wire, and then the TWO parts you see in the photo that screw onto the Sicce controller after you assemble everything. Here is a picture. And you'll need to make two small jumpers.

Next is a photo of the cable with the jumpers installed. You need to bend them to 180 degrees.

Here is a pic where you can see the RED wire is going to Pin 3 with a jumper to Pin 4.

Finally, here are two pics showing the completed cable. The black wire goes to Pin 1 with a jumper to Pin 2.

I want to give a shout out to Richard (BR260354) for the help he gave me with this. He is also the one who supplied the link to the M16 Connector from Ali Express. It's people like him that jump in here giving up their free time to out fellow reefers. And he is the reason I am making this post (just paying it forward in hopes that this post will help someonw else). And finally a shout out to my wife, who was basically my eyes and hands as these screws and jumpers are very, very small and difficult to make for an old guy
I was able to make everything and get it all ready, she put those tiny wires into the screw-down sockets while I held everthing in place as she screwed down the screws. You can see the screwdrivers we used in some of the photos. These are from an eyeglass repair kit my wife had (came in very handy). We had to use the smallest philips screwdriver in the kit.
This DIY mod works for me. However, I take no responsibilty for anyone else attempting this mod if it were to damage their pump, Kraken, or anything else. I am currently running two Sicce SDC 7.0 pumps being powered by Kraken with this mod. Thses two pumps does make the Kraken PC Board Temp run slightly higher, turning the temp numbers Orange. Here is more info about that in this thread here at Hydros Forum:
Kraken PC Board Temp Too High???
I am assured by Hydros that this is not a problem for the pumps or Kraken. Let me know if anyone has any questions, I am happy to try and help.
Ken S
) that you found my post useful. My new connector is made off of your information. Any advice or insight before I plug this puppy in? Did you pinpoint exactly what I did wrong?
