Anyone know if i can upgrade my 2012 E350 rear bumper to a step bumper with backup sensors? Currently it has a plain chrome bumper. I am assuming they are all wired the same at the factory and just get different options down the line. I am wanting to buy a used bumper with the sensors and am wondering if there is a wiring harness i can plug and play. Its a 2012 E350 15 passenger van. This thing is LONG and sensors would be a nice upgrade.

 

You need to check if you have a parking aid module, I somewhat doubt that would be included if it did not come with sensors from the factory though.

The red arrow is where the parking aid module would be.

Here is the above mentioned connector face.

This is the location of the connector closest to the bumper, this is what the sensor harness connects to, make sure this it present as well.

Here is the above mentioned connector face.

 

Thanks! Sorry to report i do not have either one of thoes... back to the drawing board. Thanks for your help! Now can you help me explain to my wife why we need to spend 5k on a set of aluminess bumpers😁

 

Do you have the two connectors I posted? This is one of those upgrades that if you have the connectors which I would assume you would then you could do the upgrade, usually vehicles share the same wiring harness even if they are not equipped with the certain modules, its cheaper to make one universal harness then to make a different harness for each trim level.

If you do have these two connectors there is one more for the backup sensor speaker to check you have, heck locate C410 again and follow it to see if it branches out into to where the four sensors would be.
If you have all the mentioned electrical connectors then I would think you would need to buy the module, 4 sensors, the sensor speaker, a bumper with cutouts for the sensors, I would check a junkyard for the bumper, may even come with sensors in it.
