Noob question; Installing intellitronix digital gauge, (tw: LOTS OF DUMB QUESTIONS)

E2 20 O to the connector is circuit E2 and no 20 wire and Orange in color. That terminal is the feed into the cluster for dash dimmer controlled dash lamps. All of them are orange, AKA radio dial, cluster illumination, or shift quadrant, etc.
So as per https://store-7fjhtq3pim.mybigcommerce.com/content/DP1805 70-76 DODGE DUSTER_DART rev12302021.pdf instructions, I can connect the purple wire to either one of those orange wires?
