So a follow up with a couple of pictures. The first picture is another view behind the gauges showing the turn / hazard relay and two unknown round black relays (any ideas?) It's an RoW vehicle so doesn't have a buzzer or seat belt warning system installed.

The next two pictures are from the cleaning of ground point G116. It was very awkward to get under all the wiring harnesses, so I used tie wraps to lift them up and attached them to the hood shock area. The area under the ground wires was quite corroded as well.

Hope they help.
