Mazda noob here and am wondering why the FSM schematic and connector pin out for the airflow meter only deal with 5 pins and not 7 as the plug and air flow meter are both 7 pin connections? I think I have THA,E2,Vc and Vs located but don't know for sure yet and am confused with the other two wires which are Br and B.(first two on the left)
The question here is does anyone know all 7 pin out connections? Are the two copper/gold colored pins on the air flow meter E2? Please correct me if I'm wrong on anything here. I assume that, Br/b=sensor ground, Br/w=+5v, B/Y key on 12v, W/R key on 12v, B and some B/W are grounds. The plug I am using is left to right Br,B,B,Br/w,B,G/L,G/O. The B and G/L are on the gold colored pins? and I assume G/O is THA.(last pin on the right) These parts are supposed to be 1990 or 91 13BT. Thanks for any enlightement on this issue. |
7 pin = s4, its got the fuel pump safety switch in it
S5 is 5 pin. |
