Just bought a used plug and cable as my current one lacks that, not sure how to connect the 3 pin 4 cables though and which is which. Would love a manual, but got none.

What is yellow? What is blue? I assume black is negative and brown is positive?

Have a pic:

Even the data wire needs a return path. It can be the Blue / Neg wire or possibly the Black which is probably wired to the Blue at the plug. They probably give you four wires at the tail because the Seatalk and Power sources are not necessarily in the same place.

Seatalk uses the negative.

Thanks for conformation, so the Black could well be the Seatalk negative.
That's not what i said. Every Seatalk device has three wire, positive, negative an data (yellow). If you have multiple devices you could simply connect all of the positives together, along with a 12v positive, same for all of the negatives and connect all of the data wires together. No need to run an additional negative.
