Anyone here that can help - pump not activating

[M3GTttHulk]

Hi guys,
Sorry to be writing here in the HSF-4 section, but it seems that the HSF-3 section is dead.

I am having problems with my pump not activating. System has been in the car since 2013 and worked fine.
I can activate the pump by hard wiring the relay at the pump, but it seems that the signal from the circuit board is missing, even when trying to activate the pump via a jumper.

I am wondering what voltages should be coming from the circuit board through the "Trunk" harness to the relay activation (red and blue wires)

Admins just delete or move if not allowed.

Did a continuity test from the plug going to the circuit board on the Blue (Trunk) harness and to the harness end in the trunk going to the pump relay (red & blue) and the level vires (yellow & black).
Looks like I found my problem, I only have continuity on the yellow wire, so it looks like my harness is compromised somewhere. I have started tracing. Just feels weird as this is a car I use 800-1000km pr year and have not done any work on this part of the car for a long time.

Fixed, Trunk harness had unfortunately been pinched under the passenger seat railings
