Riley Mk3 Wiring Loom location

Im just about to put a new wiring loom in the elf but I need to know where the loom goes after the Voltage regulator and small fuse box, that's an easy point to start with . I would love a picture of the fire wall area showing the loom where it enterers the cabin would be great, the rest I can work out. There is a hole in the fire wall where the wiper motor goes, does the loom come through that for wiper motor or run along under the top of the fire wall. tks richard
