Simon,
On the 94 WRX the MAF sensor signal line is B43 - 9. The oxygen sensor is B43 - 6. The easiest way to find these connectors is to locate the two power feeds b43-2 and b43-13 these are thickish yellow/blue cables in the right hand connector block on the ECU (the bottom connector when mounted in the car). I connected a Lambda link to the Oxygen sensor to give AFR.
All information kindly supplied by Bob Rwale at BRD.
