  there are 4 coloured wires used , red black blue and green, there are others but they are un used. on the back of the nokia acu 8152 it says ground pulse +5 volts motor a and b. so 5 holes for 4 wires. i'm sure +5 volts wasn't used. simple logic would sugest red and black would be motor a and b, greed would be ground and blue pulse but its just a guess. i could get to the motor with difficulty i supose, not a fan of ladders although i did install it myself in 1996.

  "barn door" advice:
  1. take a photo of the connections.
  2. Make a sketch of the connections and photograph or scan it.
  3. Label the connections.
  
  Keep 1 & 2 in a "Nokia ACU 1852" folder on your computer in the same directory that you keep a list of all equipment serial numbers in case of theft.
  
  5. See http://www.your-book.co.uk/position.htm

  yes, red & black is usually for motor a/b & green/ blue = sync.
  
  +5v should be to drive an optional optical sensor between +5v & ground.
  
  then there's which way round for the red/ black - get it wrong & you might have to re-sync all sats
  
  so the question is, do you feel lucky well do you:D
  
  got one circa that age, pm & jack though- over a main ridge off a gable
