It looks like the wiring harness changed since 2005. I also see the triangle bracket is gone - bolt holes are there but not the bracket.

I presume you followed the cable back and there are no connectors anywhere easy to see at any rate.

If so, that is probably for the better as those connectors were a trouble spot.

I think I am out of ideas as to where best to look for any cable damage then.

Generally the 2008 three was to my mind, the best built; in 2009 they started to try out proposed 2010 LR4 systems; not all worked well the first try.
mine is a 2007, I am continuing my search for a frayed or broken wire. Tomorrow I will check continuity from connector to connector. Still waiting on the iid tool...

Default So here's what's happening!!!
Here is where the interesting connector lives, it is below this one. it's actually one of the ones in your photo that I couldn't find. In MY07 it is behind the LH headlight.
It also housed the exhaust valve wiring, pin #1 and 2, black and white for power pin 1, blue black for ground pin 2.
Here is the diagram I am using from alldata.
we are getting somewhere...

This is the connector that has the exhaust valve power and ground wires. Pins 1 and 2 respectively. When checking for continuous power or ground, I have neither, unless I pull the F26e fuse, then I have some continuous ground on the power side. No ground on the ground side. Now when I ask the exhaust valve to open the power wire starts to supply ground at a rate of 7.x volts...has to be a short somewhere.

So for fun I made sure I have continuity at the pump itself and sure enough that harness is fine.

Are you referring to that green wire between the red and yellow conductors - the green does look broken, and no, I looked but did not see it until you mentioned it. Is that connectors C2559/C2560?

That must matter - a broken wire is no minor matter.

I am impressed with your ability to see what none of us did.
