Ignition Key - chime

to get your lights to shut off with the key ... wire in this relay as shown.
Access the grounds to the headlamps at lamp sockets ... there is a ground wire on each lamp ( four in all ). The relay coil will only draw milli amps so you can attach to any accessory power wire. Relay contacts must be able to carry at least 10 amps ... the safety is that if the grounds short to ground worst case is that lights will have to be turned off by the lite switch as normal. The ACC wire should be fused where you attach it.
Note: relay is shown ON ... wiper arms on the right ... de-energized contacts OPEN.
