Ok here we go:
1. Remove the old wiper and the OEM connector. It will look like this - I will call this the wiper arm "hoop":

2. Then disconnect the bosch connector from the bosch wiper - I have put it next to the wiper arm hoop in this photo:

3. Then insert the bosch connector into the wiper arm "hoop" half way - see picture below:

Please note that if you insert it any further into the hoop the bottom part of the hoop will prevent you attaching the bosch wiper to the bosch connector.
4. Then clip on the bosch wiper to the bosch connector - see photo below:

5. Then push the bosch connector fully into the wiper arm making sure the wiper arm hoop goes through a gap in the connector and you will hear a click:
