A method of manufacturing a rearview mirror assembly for a vehicle includes providing an electro-optic reflective element and a back plate. First and second spring-loaded electrical connectors are disposed in respective passageways of the back plate. A circuit element is provided that has an electrically conductive trace electrically connected to control circuitry. The back plate is attached at the reflective element, and the circuit element is attached at the back plate. With the back plate attached at the reflective element and with the circuit element attached at the back plate, the spring-loaded electrical connectors are biased into electrical contact with a respective electrically conductive element at the reflective element and a respective electrically conductive trace at the circuit element to electrically connect the electrically conductive trace to the electrically conductive element.
