The first few projects for the van conversion are being planned and it is time now to dig into the installation details of the rear sensors.
They fall into two categories: Ultrasonic and Electromagnetic sensors. I chose the latter and you can read why, here.
The entire unit consists of a small processing unit with leads to a small speaker, to the sensor strip and to an available 12V power source.
12V is ordinarily originating at one of the backup lights; that’s discouraged with the new Ford Transit. Instead, obtain the backup signal from the trailer towing harness. I’m lucky to have the towing option installed and the following is a detailed description of its location. Those Transit owners without the trailer tow option installed or those entirely without trailer tow wiring should follow slightly different path. ProMaster and Sprinter owners should follow their manufacturers guidelines.
When the connection is established, I have to find an convenient route to the bumper. I’ll follow the trailer harness to the next cross member of the chassis, where the wires exit to an existing grommet and enter the cross member.
Unfortunately, the lights at each end of the bumper may restrict the effectiveness of the sensor somewhat, as the sensor strip only fits between the lights.
By now, I figured out where all the components are to be located and all the parts and materials are in my possession (except for a few that I’ll buy before the installation) and the modification should be child’s play, except for the unexpected.
During the next few weeks, after the USB project, I will jump-start this little project and I’ll let you know in advance when you subscribe to my LIVE feeds. You’ll have the opportunity to view every step of the installation LIVE on Youtube, while answering some of your questions too through the accompanying chatroom.
