Spent the past two days working on the electrical plugs under the rear seat. The plugs are for the GMU11, trim motor, beacon and cabin lights. The GMU11 plug caused issues because I had to ensure the shielding was grounded across the plug. Lucky I had a spare pin in the plug, so I installed shield grounds using solder sleeves to the spare pin, it worked out very well. The other plug had cabin lights ( 2 X wires ), trim motor ( 5 X wires ) and beacon ( 4 X wires ) all in the one 12 pin plug. ( 1 X spare ).
