You have to look at the wiring diagram
Power Distribution
Central Junction Box
Auxiliary Junction Box
Each will have the relay named (probably abbreviated) and the relay number. I believe the relay numbers are embossed on each box but not 100% certain. For relays that might be mounted elsewhere, you'd need to search the wiring diagram based on the issue you're having.
