Sorry to disagree with tockworth but unless brute force is used then the plugs cannot be fitted to that board incorrectly apart form the live & neutral. I think you will have 3 x 2pin connectors, 1x5or6 pin & 2 single wires, live with an insulated spade connector & neutral with an uninsulated spade terminal. The 3x 2pin connectors should be 1 with 2 red wires, 1 with 2 black & 1 with a black & a blue. The biggest connector will obviously go in only 1 place & next to it should be either the 2 blacks then the black & blue or the other way round. The 2 reds should go at the other end of the row. If you look closely at the ends of the plugs they will have a thin web that slots into the board & should only fit easily in one position(NOT NEED TO BE FORCED). Also if you look carefully at the edge connector on the board you can see where the conductors have been marked by the plug terminals that have been pushed onto them. The live & neutral will go the wrong way round & I think if I remember correctly the live goes to the L.H switch terminal & the neutral goes to the R.H. If when you have reconnected everything it does not spin when you select slow or fast spin, then reverse the live & neutral. The other problem you may have is if the board has lost it's progamme while being disconnected for so long. If this happens PM me & I will send you the sheet that tells you how to reprogramme.
