I took some pictures today because I noticed a few things that may or may not be part of the problem...
I noticed these two slices on the connector in the trunk - they don't seem to have damaged the wire - but I should probably fix this right?
Is there a way to remove the wires without damaging the plug, or is that a waste of time?
This is from the left back-set of the car. If you look at the arrow, you'll notice a ground wire missing - should I be re-attaching it? I wasn't able to find the wire itself - but I only looked briefly...
