Connect the power feed from the fuse panel to the common terminal of the steering-column control lever, then route separate conductors from the left and right output contacts to the front and rear indicator lamps on each side of the vehicle. In most passenger cars the supply line carries 12 V DC and passes through a flasher relay before reaching the column lever. The relay produces periodic current interruption at roughly 85–105 flashes per minute, which creates the visible blinking of the lamps.
