You can alway go ahead and add it to your collective especially if you have battery for backup. The ports are all off until they are setup so there would be no problem adding the cable with it on as long as the port is off. Just make sure and power down the collective and the Kraken when hooking up the command bus cables. Also make sure the Kraken is current with the firmware on the collective before adding it to the collective in the app.New to the forum! Glad I found it though! Been on reef2reef for a while. Appreciate this info! My kraken has been sitting in a corner because I didn't realize it wouldn't come with any of the force or drive cables. Rather than spend upwards of $200 for cables alone, I decided I'd search online for a diy guide. Didn't find any guides, but the pin out you posted is all I really needed!
Here are the pre wired connectors I purchased on Amazon. A lot less expensive than the $15/pop from hydros.
Will update here after everything arrives and is put together!
