Original 1968 & 1969 Camaro Rally Sport hide away headlights were controlled by vacuum and this relay was basically the heart of the whole system. This hidden headlight relay valve controls when the headlight doors open and close. It also has a maintenance switch when you need to open the doors to replace a head light sealed beam bulb.
This is also the correct relay for 1968 & 1969 Impala and Caprice with hide-away headlights.
