A few general tips for installation on my part:
* Before drilling a tape stick to the bumper and on the marks for the holes to make (you can easily tear off again and repair)
* When using a towbar I stayed away from this with the sensors to faulty beeping to avoid the left and right approx 30cm
* The red-black wire for the power supply I always soldered to the bulb holder: Zinc scrape with a screwdriver and go
(Has proven to be very practical)
Tips specifically for installation in the Ford Focus Estate (Year 2003)
* When mounting space of little "control box" I recommend the compartment that is in the trunk right rear. There you can stick this box with the tape to the metal jauntily, then looks neat and tidy.
* This course is also handy because on this side of the reversing light - there the power is tapped :-)
* The display I have seen on the rearview mirror glued. (Looks nice from)
* From there you put the cable to the windshield above the headliner to the A-pillar.
* The panels are all just stuck, a breeze.
* In order to bring the cable from the dashboard to display the A-pillar easiest over, I went as follows:
By pushing * wire from the bottom up to the A-pillar
Stick together * cable upper end of the wire by insulating tape
* Gently by pulling it down
* The rest is easy, pull cable from the display to the rear, plugged together, the rest according to the instructions (if you need the ...)
CONCLUSION:
They work great!
The price is a stunner!
I would like the parking sensors BUY AGAIN!
