Fuel guage r32

[OO Dan OO]

What colour is the fuel sender wire on an R32? 
And how to test if it works. Pretty much nothing but the lights in my cluster work so it's possible that is at the cluster end but I am potentially just going to add an aftermarket fuel gauge.

Hmm I would have though some of the dash stuff was worth having working in a mega dollar classic like an r32

Anyway, judging by this pic all the wires are black, but at least you can find where the fuel sender is, looks like pin 6 to me

Sorry I should add, all of the tracks are marked on the back of the dash too if you want to double check

Any ideas what colour from the tank? Or how to test wires to see if the guage moves. Ther wires from the tank looke pretty hacked but I can see some snipped wires 1 possibly for the sender

Which one of these is for the sender

I have posted the R32 wiring diagrams. The wire colours are visible.

hmmm totally different to gtr, and it looks like there has been a distinct shortage of love there at some stage.

From GTSBoy's wiring diagram post

Assuming GTST is the same as GTS4,  6 is the earth, 4 and 5 are the power and earth for the fuel pump and either 3 or 2 is the sender signal (the other is the low fuel warning light, from the symbol I assume 3 is the level sender)
