You can get ceramic H4 connectors from eBay see here https://www.ebay.co.uk/sch/i.html?_from ... s&_sacat=0

Thanks for your advice. Any idea which ones I should be buying, or are they all the same?

The headlights on our Bongo keep dropping out, and it would seem that the actual wiring block block itself, is perished. Does anyone know where I can get a replacement, or do I need to replace the whole unit to get that connector?
