Evo ecu

[EVOMING]

Hello there,

My name is Ming living in holland.

I am now installing the HFS6 and got a question. I am installing on an Evo 8 and getting confused.

Looking for the connection yellow plug red wire to +pin injector on my ecu is injector 1= pin 1 / inj. 3= pin 2 / inj. 3= pin 14 / inj 4= pin 15. this one i have found.
But wich pin is the negative - for these injectors?

And wich pin is for the MAP or MAf signal?
Is this the sam as air flow sensor on pin 90?
