Below is a schematic of convolute conduit I devised for the wiring of the majority of Rover 10’s & 12’s. Also below are the wiring diagrams which I have colour coded with the colours used at that time.

The convolute junctions and the slit convolute tubing was sourced from "Hilltop" products. (link below) They were most helpful and shipping is free with any order over £50.
