Hey
Kev H
I tried to take as detailed pics as possible. Hopefully my phone is good enough...
Front cluster:
That's the front dome. Small tabs in blue holder can be taken out and wires from the bulb can be attached to them. Then just insert them back. Mind that they are very small and can be lost easily. I am not sure if You can purchase some holders on ebay or else...
Rear dome:
Hope this helps Kev
