Quite correct mate,it was the feed from the fuse box to the obd plug. Brown wire in the main loom which passes through the bulkhead,runs under the heater to the obd. From memory there is also a splice which feeds the Hevac.I think if you unclup the expansion tank and look underneath there's a plug under there where @tomcat59alan found a break in the past. Good place for a rodent to nibble too.
I saw a woodmouse in one of mine the other day. Bit nerve racking!
