Changed priint head, where do the connectors go?

[Billzilla]

The original print head on my Flashforge played up badly a while ago so I changed it for a new one. (long story)
I thought I put all the connectors back into the right place but (from memory) the wrong fan started up when the extruder warmed up. Does anyone know which plugs go into the right connectors? There's three pair of two I think, I must have a couple swapped over.
Yes I could just swap them to work it out, but if someone already knows.
