There is another earth on the drivers side footwell

Pictures of the ignition block would help as it may be a case that the loom is from a different year car or a different model spec

Also, what year is the car? And they have 2 different basic looms for low spec and high spec cars as well as different for injection and non injection plus the high spec loom also comes with door and warning sensors plus various different bits and bobs based on what was fitted to the car at the times oso a cat and non cat loom on the later cars are noticeably different

You also have 3 sets of different loom plugs across the years, round, square and triangular as the years go on so its very easy to find the fault, but if you have the wrong loom it may be easier to wire the whole loom in correctly for starters
