de toute façon il faut que tu installe ton kit large bande:
1-la sonde,
2-le cable de la sonde qui va jusqu'au mano,
3- le mano et son alimentation a récupérer sur un 12V costaud après contact.
4- ramener le câble de la sortie analogique de ton mano a l'entrée de ton boitier sur le fil signal d'origine de la sonde mazda.

tu n'as pas eu le descriptif des prises connecteurs sur l'ECU avec ta doc?

This lambda sensor operates only in combination with a special
LSU-IC, used in most Bosch Motorsport ECUs and lambda control
units like LT4. You’ll find this unit and more on our homepage at
Accessories/Expansion Modules.
The lambda sensor should be installed at point which permits the
measurement of a representative exhaust-gas mixture, which
does not exceed the maximum permissible temperature.
Install at a point where the gas is as hot as possible.
Observe the maximum permissible temperature.
As far as possible install the sensor vertically (wire upwards).
The sensor is not to be fitted near to the exhaust pipe outlet, so
that the influence of the outside air can be ruled out.
The exhaust-gas passage opposite the sensor must be free of
leaks in order to avoid the effects of leak-air.
Protect the sensor against condensation water.
The sensor is not to be painted, nor is wax to be applied or any
other forms of treatment. Use only the recommended grease for
lubricating the thread.
