Go to the Simrad website and search for the WP5000 owner's manual. It will describe what the wires are for. If I recall correctly, red and black are power inputs for operation with the control system compass, and the other two are for inputs from a wind vane transmitter.
I've just been given a unit that came off a Hunter 340, and it has only the black and red wires, so I assume that the previous owner did not have a wind vane tied into the system. I haven't tried to install it, so I don't know the answer. However, if you get it to work, please post what you did.

Navico WP 5000 Wiring
I've got an old Navico WP 5000 with a power wiring harness nothing like in the user's manual. It has the standard red +/back- wires, and also a white & bare wire.
Anyone have a clue what to do with these latter 2? With just the + & - connected, the drive unite doesn't power up.
