Thanks for all the kind words.
I have noticed a couple of things when trying to sort the lights out.
The indicator in the up position wasn't quite making a good connection. Stripped it and cleaned the contacts, although I found some of the parts are quite worn so it still isn't perfect, have to push it up a bit harder than id like to make a proper connection.
The heater fans do not work, I'm assuming it's a fuse but this won't be needed for the MOT anyway.
The front marker lamps also do not work.
The ignition barrel has been replaced at some point and rather than the two wires coming from the top part of the barrel having a male and female spade they are both male. Looking at a wiring diagram I assume all these are for the door buzzers - well it needs new door jamb switches anyway unless I can fix the ones I have.
Brake pedal is good although I've ordered new hoses all round as on quick inspection they look a bit perished.
Could do with finding a new metal front headlight surround, I have the old plastic ones off of my old car but they aren't correct for that year.
Cheers,
Dan
