you need to look at the correct wiring diagram 
the mod gives a clean earth to pins 3 and 6 of the MAF sensor
Pin 3 is ground ref for the IAT sensor
Pin 6 is ground ref for the MAF sensor
these earths before the mod are shared with the twin signals from the TPS sensor
the early HDI looms suffered from poor connections within the loom (common crimp point joints)
the side effect of this was the ecu would log a inconsistency fault on the TPS and the IAT sensors
the earth mod would fix it
the mod itself is a Peugeot FIX so it is a recomended fix from factory
