how have people installed and wired their slimline fans?

[P-Courty]

If you look on my thread i've devised a wiring plan for mine, going to be 3 way switch - off, both half speed, both full speed. Also when you linked the relays did you give the fans a little knock of persuation as mine are free by hand but when tested needed a little knock to get them going.

EDIT:
I also have picks of all the different relay link up to try fans, either 1 or 2 and different speeds.
