Maybe try this out:
https://discussions.apple.com/thread...rt=30&tstart=0The pins of the 4 wire pump are connected as follows:
1. +12V (V control)
2. Tach output
4. V mot (variable)
6. ground

So if i read correctly:
That the wires that need to be connected to run around are the (from left to right); ground and the 4th post or post #1 (+12v) and the 3rd post or the tach output for rpm readings.The swiftech pump originally comes with 3 wires, black (ground), yellow (+12V) and blue (tach output).
Tried that and alas nothing...now i'm trying the posts that certain swiftech's are soldered to see if that works. If i fry a board, sure i'll be disappointed but at least i walk away knowing that didn't work.
SOLVED THE PROBLEM!!!!
Almost wanna make a reference page or something....any pumps that you get off of ebay or anything like that (that are apple oem replacements,) or are laing ddc boards version 5.4; just solder a wire to the ground post/slot, and the post/slot directly next to it.
If you were looking at the board and solder points:
GND[x] [x] [] []
Thread can now be closed, thank you.
It was just trial and error testing to see what worked and didn't...i was prepared for a board to go up in smoke, but alas it didn't.
As far as i know, the laing DDC 5.4 and 5.7 version are "somewhat" similar, however, if it is a 6.0 i'm not 100% sure they use the same posts.
If you need to see where the version is printed for the 5.4 and the 5.7 board, refer to the picture posted on page 1, but on the v6.0 it is printed to the right of the 4 main solder points.
My assumption is that all the swiftech boards should be v6.0 brand new, but second hand ones will most likely be the older versions.
What is awesome is that every forum i've seen hasn't had the answer to this wiring problem anywhere...TBCS is the only one now...as far as i know of.
