Vehicles with spare wheel on rear door:
The Taurus parking sensor when fitted to vehicles with a Spare Wheel on back door (i.e. 4x4) will only utilise Zones 1 & 2, as the depth of the spare wheel takes up Zone 3 (nearest to your vehicle). However this does not affect the overall accuracy and performance. We have fitted many T123M parking sensors to these vehicles without any problems.
Vehicles with a Tow bar:
Taurus T123M is the recommended Parking Sensor for vehicles with a Tow bar fitted as performance is not affected.
Technical Operation:
When reverse gear is selected the small control unit generates a magnetic field and transfers this to the transceiver adhesive strip that is placed on the inner side of and run the length of your bumper.
The magnetic strip then sends out an elliptical magnetic field to cover full the area around your bumper. The transceiver strip works by sending and receiving unlike Ultra-sonic parking sensors that require 2 types of sensors, one to send and one to receive; if they become dirty the ultra-sonic performance can deteriorate. This creates the field.
Mass is then monitored by the control unit by translating this into a voltage. When an object (i.e. people, kerbs, cars, etc) heavier in mass than the magnetic field enters this elliptical zone, an increase in voltage is detected by the control unit and you are then informed by a series of audible tones how close you are to the object. You can then manoeuvre accordingly.
Installation:
The T123M parking sensor has an easy 3-wire installation.
1) Earth connection that is picked up from the body of the car or from the earth wire going to the rear light cluster.
2) 12V wire connects to the reverse wire going to the light cluster that is live when reverse is selected.
3) The adhesive strip has a wire already attached that you simply connect to a wire coming off the control unit.
The adhesive magnetic strip is must be placed 3cm away from any metal strips that may be on your bumper and 45cm from the ground. The majority of car bumpers are ideal to have this positioned at the top of the bumper.
In many cases your bumper may need to be removed (dependent on vehicle) in order to mount the adhesive strip. But this is a lot easier than it sounds.
If needed we can provide you with bumper removal instructions for the majority of cars or you could consult a Haynes Manual or ring your local car dealer and ask to speak to a technician in the Service Department. If required email us your make, model and year of car (after ordering) and we will send you a copy of the instructions (if we have them available).
Professional Installation:
If like a number of our clients, you would prefer a professional installer to carry out the installation for you, I would recommend you look in your local Yellow Pages (Car Electrics & Car Audio) categories or visit Yell.com to find an installer in your area.
