With thanks to someone on the brown forum throwing some wire my way, it was more than enough to make the little extra bits I needed to connect the new lights to the car's harness. Nothing fancy, just turning a single output from the harness into two outputs so I could feed both headlights. It was so easy even I could do it. Now all the lights work and I've removed the MG B units so the front end is looking a lot cleaner. Still undecided on number plate location, I did try it out on the front valance and the plate is too big, standing it up looks okay but blocks a lot of air feed to the radiator so isn't ideal, current location might end up being the best compromise. A smaller plate might work better, or an offset square motorbike style plate (although a 6 digit reg would be better for that, and I don't really want a private plate).
The other thing of note is that the inner pair of headlights shouldn't really have dipped beam. I need to either de-pin the connector or split the feed wire to the dipped beam or something, it's not urgent right now.
Sidelights.
Dipped beam.
Main beam.
Dipped beam with indicator.
Hazards.
One thing I do like is because of the shape of the headlight outer lens and the fact the units are pushed slightly further forwards than the originals, you do still see the indicators a bit from the side of the car. I'm probably going to put a side repeater in at the front of the wing when I can find one I actually like and I'd put that ahead of the front wheel arch rather than above it since it would be more visible there given how long the nose is on the Princess. I've also got to do things like blank off where the MG B units were and return that strip to factory, then tidy up the paint and whatnot.
