Patience is a big plus when decoding/tracing wiring on a Morgan!
I print off a copy and use coloured highlighters to trace the wires I need to follow then compare them with what is actually on the car! idea
I keep them afterwards in case needed again (with notes added on).
For my Plus8 the Gomog file splits the wiring into 3 parts....
front/engine
Dash
Rear.
