    Default Laing pump pcb wiring

    I recently acquired two pumps that were in a apple g5.

    The pumps are laing ddc pumps. I was wondering because the directions that the seller gave were un-clear because he gave no picture, but if were to run the pump "pc version" which two wires do you keep soldered on?

    Is the the farthest left and the one next to it, if were looking at the pump from the inlet/outlet side or is it the reverse?

    The first option is what i have it at now, i just thought i should double check before i run these pumps.

    I believe they are the DDC 1-VC 10w but I honestly do not have a clue...but here's whats inscribed on the board:
    LaingDDC v5.4

    4 solder points:
    Gnd scribed to the left of point, blank, blank, and blank.

    Could it be gnd, +, speed and then blank?

    There's a pump mod kit that replaces the circuit board on those I've got a how-to about that should be published soon. Your pump is the right age, I would say that the kit would be an excellent upgrade for you, and as a bonus the wires are very clearly labeled on it.

    It basically replaces the factory board with a board that has clear displayed posts, quicker start up, and fancy things like led lights with it.

    I think i'm just gonna go with trial and error. If anything thing i may be able to switch out the board if the board fries.

    Start off with low voltages. ~2-5V.
    Two years. They were great. Let's make the next ones even better!
