- With no manual, wires coming from the fuel gauge have to be tested by measuring their current, then reducing the amount of fuel in the fuel tank and then measuring '''current''' again. The wire that has reduced '''current''' in response to less fuel is the fuel sender wire. All the wires have to be measured between each change in fuel level. The fuel sending wire is typically red or pink, but this is not guaranteed to be true

- A more direct way of finding the fuel sending wire is to take out fuel sensor from the fuel tank and move the floating arm from full to empty while measuring the current of the wires. This should be done with electronics on and without ignition (key in ACC position). Fuel tank should also be empty for safety reasons, and trying to turn ignition on in this situation is likely to damage internal components.
