Mk2 Heated rear screen
#2
Hi Kim, It's behind the fascia with the switch and lamp. The relay does not control the actual heated rear screen, it only dims the lamp for night driving, the relay is energized by the side light circuit. Early models did not have a switch or relay, the heated screen came on with the ignition. The switch and lamp were added early 1966.
Hope that helps.
