The circuit has been double-checked and verified.

This gear indicator should work on all Suzuki motorcycles with a gear position sensor. I believe most Suzuki models 1996 and up have one.

Schematic showing location of resistor for bikes with HARD WIRED TRE mods.

If you want to use the gear indicator with a TRE, you have to put in another resistor. It will not work with switchable TRE's. Well, it will only work when in one position or the other, not both. for example, if your GPI is set up to work with the TRE, and you turn it off, the GPI will be one gear too high all the time.

For the TRE assuming you hard wire it: You want to keep the blue wire in its original state. You will cut the black and pink wires. I suggest doing it on the sensor side of the connecter so if you want to go back to stock, you only need to buy a new sensor and replace all your cut wires easily. Then, you want to put the resistor across the pink and black wires going to the ECU. The TRE would then be complete. To use the GPI, you would connect the wires in my schematic to the wires going to the sensor. The extra resistor in my schematic is where the voltage comes from to make the sensor continue to be functional even though the TRE is installed and the wires do not connect to the ECU.
