I agree with Fizzy, I have carried out the loom fix and took it a step further by adding a large diameter earth cable from the loom fix green wires to the frame earth. After that  I got an Fi light fault and I checked the ECU plugs and found one of the earth connections was corroded, it looks like the water entering the loom fix connector had wicked up the cable. I found that moving the wire in the ECU plug made the Fi light go off and on. It seems the loom fix issue goes beyond the connector on
