Hi Robbo sounds like your having fun, I think you will find original loom for your PR was F2, I used a Haynes and have also used a clymer blow up. But I always go through it all with multimeter and write it down bit by bit get one part working at a time, I normally remove silicone diode when testing with meter never sure if you could harm it also have battery disconnected. Wiring is a sh*te part at times.
