This earth point was a real s*d to get in place; I should have worked out where it was going to be and installed the rivnut before the fusebox etc was in place. It takes 3x earth lines - battery, chassis loom & engine loom.
ECU now in place and cables roughly routed - its just about working - I'll install some cable ties to tidy things up in due course when I'm sure nothing is coming back out.
I still need to work out some safety covering for IVA, to ensure no sharp angles can be touched by occupants. The wiper motor might also have to come out - depends on which way the wipers park.
