Dubplate.....pressure!! (Cool name) - I have made some progress - ok this might be a bit of a long explanation and i hope you remain patient with me:
OK the main choc box that plugs into the back of the head unit has fixed wires and others (which look optional) - out of these wires is a red one but this does not plug into anything - its free but does have a male connector at the end of it - there is another red wire from one of the black connector boxes which is female - so only if you connect the two is there a connection.
Again from the main choc box that connects to the back of the hu are 2 wires a blue/white one & pink/black one. Not sure what these do but both are female. however there is one last wire that needs some explanation. Again as with the red wire there is a male coming out of the main choc box and a female from the connector - this connector btw has on it the following: a black, a blue, and a red and a yellow. The black and the blue are directly connected but the yellow and red need to connect with the other yellow and red to complete the circuit - Apologies for the essay - but i am guessing that if i connect the two red ones and the two yellow ones i will get a complete circuit - hopefully..... (If you know what the yellow does i will be much obliged)
