I am installing a dual screen G3X system in m RV8. I have dual ADAHRS but a single OAT probe. Are the ADAHRS designated primary or secondary?

My real question is does it matter which ADAHRS I hook the OAT probe to? Wiring considerations dictate I hook it to one over the other but I'm not sure if that will have implications during setup later
Thank you
Bob

It's all buried in the manual:

Unit ID:
ADAHRS #1 Leave pins 4 and 5 (of J252) unconnected
ADAHRS #2 Connect pin 4 (of J252) to pin 5 (of J252)

NOTE:
For installations using more than one ADAHRS, ADAHRS 1 must be connected to a GTP 59, but installing additional GTP 59?s for other GSU 25 ADAHRS units is optional. An ADAHRS not connected to a GTP 59 will use temperature data supplied by other ADAHRS as long as both ADAHRS are communicating via the CAN bus.
