Rb25 series2 3 pin mass air pinout?

[jacksonbrown]

I have a series 2 and the only schematics I have found dont show a 3 wire mass air. I also need some help with this plug below. I had someone tell me this was for wiring the igniton but wondering if someone might have a little more info. I used the 8 steps on NICO and double checked against the rb and 240 schematics and I'm still having some probs. Tach does'nt work, if you turn the key but dont start the oil, seatbelt and check engine lights stay on even after the key is removed. Also car will rev up to about 2500 then acts as if ignition dies till about 600 rpm and picks up again.Running extremely rich. Thanks for any help

Hey thanks alot. Solved multiple probs with that. I had all three wires wrong on mass air. Runs pretty good now. Also think I have bad ground in dash wiring, went to hook up radio and ground in factory plug was infinite may explain no tach and idiot lights not working correct.
