Looks like that's a generic 4-wire sensor so you have to splice the connector.

This one is the correct part cross referenced by the original number (077906265J), and is the same price.

well they arrived and look like the correct part but looks like you need the arms of Mr tickle and the hands of a newborn to get to them.

Anyone any tips or links to a guide for this job ?

MJ is no doubt the expert on doing this, but it can be done by mere mortals as well. I did mine a couple of years ago, once I managed to find out where they were. Not sure of the correct procedure, but removed the driver side one from below. The passenger side I got to from above, but that resulted in some blood loss and bruising.
