I purchased a new sensor and, How do I get it to program with my system. Should it have a number on it to know which sensor that it replaces. I need it to replace my #1 front trike wheel.

Pairing your new sensor should be in your manual. If you like a copy, please respond to this email, and I will send it to you.

Pairing new sensor:

1- Turn on the head unit (press and hold the lower button)

2- Press upper button 5 times to enter pairing.

3- Choose the wheel to pair by pressing the lower button (flashing wheel)

4- When the desire wheel flashing, install the sensor.

5- Once the new pressure is showing, press and hold upper button to save and exit.

I need a replacement sensor for # 1 sensor of 670 system. Will this work??? Does it need to get reprogrammed ? If so, how does this happen?

Yes, this item is for replacement of your sensor. Numbers on the sensors are for refrence only. they are handy when you just get the system and helps to installed the sensors accourding to the defualt settings. Once you receive a new sensor, you will need to pair to your head unit. If you wish I can send you a manual to show how to pair as well.
