Here is a quick instructional tip that will save some trouble when trying to set up the aRacer quick shifter on the 2017+ SV650. Since the module plugs directly into the stock 02 sensor location we need to change from the R3 connector included on the aRacer quickshifter to the connector from the SV650 stock O2 sensor and arrange the pin in order to get power, ground and signal all in the correct locations.
First, we need to de-pin the connector on the aRacer Quickshifter and the stock SV650 O2 sensor. The good news is the terminals are the same so the pins and seals are interchangeable.
The connection is pretty straight forward.
Here is a photo of the stock O2 Wiring for reference.
Here are the wires we need to focus on the location we will blank.
Here is the corrected plug with the wires from the aRacer connections located correctly to function.
After moving the pins you'll be able to see the shifter under the parameter NBO2_AD in the variables to set your pressure for the quick shifter.
