The headlamp relay switch is a high quality reproduction of the original GM switch assembly. The unit works with the headlight switch on RS models to enable the headlamp door to open and close when activated.
The relay switch includes the correct hose outlets for the vacuum hoses to connect to. There is an open and shut valve on the relay which opens and closes when the headlight switch is activated.
This is a cosmetically correct reproduction and will allow your headlights to operate as original.
