I dunno how much use this'll be to anyone, but I've just spent the morning re-typing the original premier wiring loom instructions (as provided by mad butcher, here) Also I've dug out some bits provided to me by the very kind Turnipfarmer.

And I've uploaded it all Here, the PDFs should all print however you like, the jpgs are there for reference in case I missed anything relevant.

I'd suggest printing them off and laminating them, because otherwise the words fall off the paper.
