Help! wiring troubles

[skwertle]

I live in the states and i'm trying to do a rb25det swap in my us-spec 240sx.

I have a series 1 motor and accidently acquired a series 2 maf. I have read in other forums/post that the maf will still work.

Problem is this. my plug has 4 wires and my maf has 3 pins. what do i do?

Thanks in advance,

Jimmy

ok, a guy in another forum just told me that 2 of the 4 wires on the plug/harness are grounds?

can anyone here confirm that. and if true what color are they?

ok, i'm pretty sure that he is right.

so, looking at the maf the pin closest to the air filter goes to power relay or ecu signal? cuz the middle is the ground, correct?

can anyone at least tell me the color of the wire closest to the air filter on the maf?
