Dim dip connector replacement and headlight relays

[jammy_basturd]

The inevitable has happened and my dipped beam headlights aren't working (I don't think). Connector has burnt out on the dim dip control box. Does anyone know where to source a replacement connector?

Also, as someone has completely botched the wiring in the past (see picture) I'm going to fit some relays and run some proper wiring for the lights. Does anyone have recommendations of which relays to buy and where? I have the 3 pod headlight upgrade.

Used this one for my standard lights. Believe they also sell 4 lamp units.

Replaced crappy fuses with something decent and took a direct feed from the battery. Links in to one of the original headlight connector and removes the high current from the light control box. Works perfectly, and was delivered quickly despite being form HongKong.
The new power feed and decent bulbs have made the lights noticeably brighter
