R32 Map Sensor Wiring... need quick help!!

[NO_RSPECT]

Hey Peepls

I need some help identifying which of the brown wires does what.

you know which is positive which is negative and which is signal (pretty sure this is the middle one)

bearing in mind i do not have a multimeter or any other equipment

and it isnt actually connected to a vehicle at the moment either

thanks

i should have made this more clear

the boost pressure sensor...that mounts on the firewall or on the left side on r32's

there are 3 brown wires... and because i am using one out of an R32... in another vehicle i cannot test what is positive or what is negative. and what is signal
