Freelander 1 L series 2.0di fuel pump wiring colors / evry mod

Hello guys! I use my LRFR 2.0 L series in the forest, so I need some more power. I did egr off, decat, and I found on this forum how to install evry mod on this car.
Following the instructions by this discussion: https://www.landyzone.co.uk/land-rover/l-series-mods.284526/

I found the yellow-black wire, but I can't find the red wirie to solder with the variable resistor.

Is this the fuel pump wiring? If the answer is yes, cand you help telling me wich wire colors should I solder with the variable resistor to install the evry mod?
Thank you, sorry for any bad english, I am balkan

I don't know where the wire is, however if you download the Rave workshop manual it has full wiring diagrams. The wiring diagrams gives colours on the wires and the connectors they go to. A separate section of the manual gives a picture of every connector so that you can identify where they are.
