the chip is for t34 turbo.

the lambda sensor i used was a bosch universal 3 wire.
the signal wire goes to pin no 2 on the ecu
the other 2 wires are for the heater coil inside the lambda sensor
1 wire needs to be earthed
the remaining wire is attached to the fuel pump relay output.
ITS THAT SIMPLE!!

i fitted this conversion on a mates 3 door and it took 2hours including welding the sensor boss into the down pipe and wiring in the sensor.
