All the tensioners on these are 2 wire and is does not matter which way they are connected.However on some the 2 pin plug can be released and on others the fly lead is part of the stalk.Remove the broken belt from the car and see if the plug can be detached.Alternatively you could cut the lead and join it to the new one.
