As requested by
greck999 here's pictures of the clusters. Silly of me not to have them in the first post, but here they are:
This is the outer/standard running light.
The red wire on the left is the one I added, which runs up the c-pillar and down the hatch.
The wire you want to clip onto is the second lowest one, grey with black line, actually marked #2 when I look closer!
You can also see the blank indicator bulb I use, which gives a whiter glow than the stock amber.
This is the hatch cluster.
You can see how I used connectors at this point, if I ever wanted to revert back to standard lights. Who knows.
