Fuel level signal query and alternator light

[Bigade49]

I have intank lift pumps and fuel level switch to wire into an M150.
I'm not sure how to wire in E and F? which type of channel etc?
This is the intank fuel connector pinouts I've been given:

A +ve Two left hand low-pressure pumps
B -ve Two left hand low-pressure pumps
C +ve Two right hand low-pressure pumps
D -ve Two right hand low-pressure pumps
E Float switch contact closed on low-fuel level
F Float switch
I'd like to measure fuel level and low fuel on the D153 dash if possible.

TIA
Ade

Is the float switch a simple switch, or does it provide a variable resistance output? If so, what is the range of resistance from full to empty (or the point at which it closes completely)?
