90 fuel tank wiring?

Hi there.
I was wondering if anyone knows what order the fuel tank spade connectors go on a 87lr90?
Here is a pic
In the pic I have numbered the terminals to aid diagnostic
tahnk you

Blacks earth so that shud be easy to find then it's a 50/50 chance of getting the other 2 right.

Cheers, I did guess that much.
I have tried several configs but gauge still no work.
Got annoied so cheated and asked LZ members
I will trawl through the manual

use a continuity tester to find out which terminal is the earth hold one end to tank and other end to terminals. then the rest is childsplay.

Cool I will give that a go.
I lost patients with it earlier.
Was tired and needed a rum

am haveing the same problem with mine i replaced the float in the tank with the terminals on tha didnt fix it. the gauge is working i think because if i put the wires a certain way the guage will say its full when its only half a tank. also when the fuel light comes on when the fuel is sloshing about in the tank it sends the fuel gauge to full.
if you find out what the problem is can you please let me no? my next step was takeing the gauge out to replace it see if that will fix it!

trial and error is the way forward. can take a look tommorow night if no one else answers before then.

Sorted it! Its
1 is Green
2 is White
3 is Black

Sorted
Fuel gauge works great and I have half a tank!

Sorry for digging a old thread up but obviously black is earth.. white and green... what’s what?

I take it one is data for the fuel gauge is the other live ?
