Hi, I hope you can help. I need to replace my front door and there is currently an alarm sensor stuck to the frame and door. I never use the alarm, so I would like to remove the sensors and connection block, without setting the alarm off permanently. I have 6 wires going into the connector, black, red, blue, yellow, green & white. only the first 4 then go up to the door sensor. Can I just remove the sensor and 4 wires or do I have to join any together? Ideally I would like to remove the connector box altogether. perhaps chopping the 6 wires. The alarm is a texecom veritas R8. Many thanks, Chris
