I had to go back and do my leads again today. The problem is not just the boot: you can see how mangled the connector has got forcing it into the socket of the Bosch cap. This is plug 5 which seems to be the worst!
In fact it is SO tight that it can't make contact: the copper tabs are forced completely straight from the tip to the end of the exit hole. There is no room for the tabs to spring. And the flat plate has started to pull itself off the connecting pin.
