I've never done it, so an extra note of caution... But I assume you would need to re-order the sensor wiring along with the main wires. Page 50 of the ROAR rule book has a sensor wire callout and diagram.
A portion, without the cartoon:
8.8.1.3 If the motor is sensored:
It must use a six position JST ZH connector model number ZHR-6 or equivalent
connector with 6 JST part number SZH-002T-PO.5 26-28 awg contacts or equivalent.
Wire sequence must be as follows:
Pin #1- ground potential
Pin #2- phase C
Pin #3- phase B
Pin #4- phase A
Pin #5- temp control, 10 k Thermistor referenced to ground potential
Pin #6- + 5.0 volts =/- 10%
For clarification pin #1 is on the left hand side of the above connector with the wires
exiting the top of the connector and the plastic tangs that hold the contacts in the
housing are facing forward. See drawing below.
Sensored type compatible speed controls must use the six position JST header part
number X-6B-ZRSMX-TK (where X denotes the style of the header) or equivalent.
The power motor wire connections must be clearly marked A, B, C on both speed
control and motor.
A for phase A
B for phase B
C for phase C
