Over the last few weeks I was working on adding rear park assist to my 2018 ram 1500 I used all oem parts except for the harness I made to go from the park assist module to the rear of the truck . I used Alfa obd and Mgrimm bcm id details from the Alfa ond diy and I now have oem rear park assist . I will post the parts I used to get the job done . It ended up being a expensive project in my eyes . So the parts are as follows Bezel for the bumpers needed four of them . Part no : 5lt35zzzaa-001 Jumper harness for the rear Part no : 680318200AA-001 Then I bought a repair kit for the connector and pins to plug into the jumper harness Part no : 68018957AA-001 Then the rear park assist module Part no 68204477AF Then the park sensor itself needed four of them Part no :1EW63TZZAA I drilled my own holes in my rear bumper . Painted the bezels chrome to match my chrome bumper as best as possible . The only part I still need is the new multi switch for the dash to add the button itself The system seems to be on automatically once I added the codes in the bcm So the harness that runs from the park assist module to the rear of the truck is the only part that i made per say . Deere guy had the two plugs with wire ends sticking out of them that i extended to get too the necessary locations .Thansk Deere guy for sending those out to me . I have been in contact with m2mods along this project . I will post up some pics with the schematic and where I connected on the truck later on this Evening . This is my first right Up so please be patient .
