This will allow full function of your stock gauge set with a Maxx ECU. Coolant gauge, gear indicator (gen2 only), ABC mode indication (gen2 only), FI light all are controlled over the data stream wire on a stock suzuki ECU and don’t work with the Maxx ECU. This adapter will allow that functionality to be returned.
***This will not do anything for your tachometer, speedometer, neutral indicator light if they aren’t functional, those are normal wired signals to the speed sensor, tach output on MaxxECU, and gear position sensor. My dash adapter is for the serial data stream wire which covers only the signals mentioned above ***
