Fix the repellent facing upwards using plastic tags. Tilt the repellent face towards the middle part of the bonnet.
Clip the repellent wires to positive and negative terminals of the battery.
The bonnet has heat insulation pad within, so paste the aluminium sticker just opposite the repellent to re-bounce the ultrasonic sound throughout the engine bay. Please request aluminium sticker from Varna Suraksha.
