Source: http://www.doksinet Step 2) Firstly like to thank Lenny for a small tip he told me  . On a Mk25 Focus on the inside of the of the rear bumper are four circle markings where the sensors if factory fitted would be , you do not have to do any scary measuring or lining up. See pictures below , as it was dirty behind there , rubbing my fingers across highlighted the circle’s There are four , one each

side above the reversing light and fog light and 2 in the middle approx 400mm apart. Using a wood Bodging tool (sharp point) , and a torch i centered the tool in the center of each circle and gently pushed and twisted until on the outside of the bumper i could feel a slight lump appearing , not pushing all the way through to make a hole. These lumps would be my guide for drilling and also to check if it looked ok before drilling. See pictures below.

Wipe each area clean and remove any plastic

bits on the inner hole to allow a smooth fitment. Step 4) Reading the instructions , the unit requires in this case 4 sensors , they are letter A,B,C and D , Starting with letter A for Near Side (above reverse) , un-wrap the cable and feed through the hole , gently place the sensor inside the hole but do not push home yet. Repeat this moving right to left B ,C and D. You do not need the supplied angle spacers.

Do not pull on the cables. From underneath using tie wraps daisy chain the cables together with the tie wraps threading through across the top side of the bumper bar and gather them together by the reversing light. Inside the boot , remove the side panel using a T25 hex driver bit , take out the two screws , then using a flat screw

driver prize off the seat belt surround plastic panel and slide it down the seat belt. Remove the boot water seal rubber and then gently pull the large panel forward until it un-clips. Remove the small panel as per the picture, this will give you access to the reversing light cable and grommet.

Then from underneath feed all four cables through the grommet, then secure the cables underneath again with tie wraps away from any metal that they could rub against.

Undo the earth 10 mm bolt and wrap the earth cable between the two ringed connections and tighten down. Remove the insulation tape from around the reversing cables and connect the position feed to the Green/Yellow cable via

a scotch lock. Plug in the power connector and Test the System.

Insert the two T25 screws and tighten up Replace the boot rubber seal making sure you pull the lip of the rubber around the edges of the panels; rear of the car is now finished.  Source: http://www.doksinet Sensors have a nice clean look to them. Step 8) The LCD control display has a AUX power plug and a stand for Dash mounting; i did not want to use the AUX plug or the stand as i wanted to fit the display above the interior mirror. Firstly cut the cable off leaving about 8 inches. Undo the four screws on the LCD and remove the back. Using a hacksaw, cut a groove out so

the cable can be moved to the top of the unit allowing it to be hidden easier. Source: http://www.doksinet Move the cable from the bottom of the unit to the top and replace the back and four screws. Step 8) Using two small flat headed screw drivers prize the interior light unit out working your way around slowly a bit a t a time until the unit comes free. Solder or join the 3amp Fused connector to the Positive side of the LCD and slide up under the head lining just above the mirror and feed the cable through to the interior light unit. Using a 10 mm socket undo the earth point bolt and attach the Black/red earth cable to the earth point and tighten the bolt down. Attach the positive red wire of the LCD to the Single wire positive of the interior light unit. Now with 3M double sided tape fix along the top of the LCD and then push onto the head lining and pull the cable from the interior light side for a tight fitment. Replace the interior light unit. Position the car in a clear

space, place in reverse with the ignition on and open the windows and test each of the sensors by placing an object at different distances away.
