Assuming you mean the Lucas 6DA unit, I used to have one on a MG Metro many moons ago.
I found it quite useful although it was just one speed.
To install it was a question of disconnecting the multi pin plug from the wiper control arm and plugging the respective bits into the 6DA. However there are some 6DA units around that have wider shorter connections.
I remember reading on this forum some time ago that the pin outs could be different as well.
If I remember correctly, you gave the wiper control a quick flick to activate it and another quick flick to deactivate it.
