The XS Expansion Loom plugs into the expansion connector present on all Link G4X plug-in ECUs, extending the available I/O for sensors and switches that the base ECU header does not provide. The channels added depend on the specific plug-in ECU — refer to the ECU’s specification for the exact expansion pinout.
Common uses:
– External MAP sensor (required on plug-in ECUs without onboard MAP — e.g. SupraLink, MR2Link, S2000Link)
– IAT (inlet air temperature) sensor
– Analogue wideband lambda (0–5 V from an external controller)
– Boost adjustment knob or trim switch
– Map switch (switch between calibration maps)
– Oil or fuel pressure sensor
