[QUOTE="jarance, post: 477636, member: 21"] New Flash!! OK, for the rear camera installation, this is what I found. 1. There are two bulbs for the Licence Plate. If you install the rear camera, you will need to remove one of the bulb and connect the camera LED to it. This will not cause any alarm on the instrument cluster. This is because the LCM (Light Control Module) will still detect the presence of the second bulb. They are wired in parallel. If you decide to change the other bulb to LED, you will get the alarm on the dashboard. There are 3 solutions to this problem. a. change to LED that are CANBUS compactible. b. Disable the monitoring by using an programmer for the LCM module. c. Add a resistor to the LED light. I have tested the resistor value and 1000 ohms will cancel the alarm. Power = V X V / R (Voltage Square divide by Resistance) = 144/1000 = 0.15 watt. Hence a 10 sens resistor would be suitable. i.e. 1000ohms/0.25 watt. or half watt if you are the kiasu type. will try for front pilot light later. stay tune for the result. [/QUOTE]
