Spent 3 hours tracing through the whole of the electrics on the car to suddenly realise I'd forgot to reconnect the earth for the hazard relay and the sidelights fault was down to a dodgy fuse. It looked fine and was testing fine on the continuity setting on the multi meter when I was holding it, but turned out that the end cap on the fuse was loose so when it was slotted back into the fusebox, wasn't making any connection. So, an evening waste
