Thanks Henry! The braided line and A/N fittings are all Detail Master items. They are about the only after market items I used on this model. For this 1:12 scale kit I used #3, #4 and #5 sizes. The clear tubing is a mixture of tubing I got from work and a few sizes I got from Model Factory Hiro. I also made some by stretching the ends of pipettes. I will post pictures of this later.
As far as a wiring diagram, I only had pictures from a couple of books. As I understand it, the Ford Cosworth DFV is essentially the same in a number of F1 cars. If you can find any pictures of the DFV from that era, it should be a good baseline to get you started.
