I used this relay - it takes 12V DC, very little draw as the coil is tiny, even a signal 12V can hold the relay, and then the contacts apply the ground to the trigger wire of the factory TV module, which is a small draw as all it is a signal ground for internal circuitry inside the module... bosch relays are for some heavy duty equipment, and the white papers should list the amount of amperage that is needed in order to hold the coil - the relay itself might be using too little or too much power.
My relay is using fraction of power (I lost the white papers long time ago for the relay), and the contacts are able to switch up to 120V circuitry,which is more than enough for the small electronics...
