In stand by mode, relay terminal 1 would be hot via the flasher.
For a RT, relay terminal 8 would be steady hot via the turn control on the steering wheel. This energizes the RT relay.
Terminals 6 & 7 would be hot via the relay contacts & terminal 1, until the current to the front & rear bulbs caused the flasher can to start operating. It is the current drawn by these bulbs that causes the flasher to operate.
When the flasher starts, terminals 1, 6, & 7 will be intermittently hot in time with the flasher.
