Hi had some problems whit my fuel gauge and localized it to the wiring connection on the fuel tank but when i removed the tank all wires was just hanging there except the earth. But now i don't know where to put them again in the connector. Everything was just corroded and bad.

It's 3 wires one blue with a black stripe, one brown with a green stripe and then a brown with a red stripe. And on the connector there is 3 digits 1 2 3
So if any one that could tell me which color to which number ?

I have looked in the Haynes wiring diagram for the Sierra but i can't figure out which number thats which color.(there is no numbers on the color for the fuel sender unit) Pretty sure i can find this in the Fords own wiring diagram for the sierra anyone have that ?

Its a Mk1 Sierra 2.0GL 1984 btw.

Any help appreciated !
