How to: Add Adaptive Cruise Control, Lane assist, FCW & Auto Hi-beam to Ram 1500

[vincentw56]

I have a 2022 Laramie that I want to add ACC and LKA to. I believe I have all of the hard parts I need.
-A used HCU and ABS module
-The steering wheel buttons
-Correct 12" center stack

What's truly keeping me from adding this is the programing needed with Alpha OBD. I've got a 1700-mile road trip coming up this Thursday and I don't want to mess up the truck. On the other hand, I have a Comma 3 and I'd really like to be able to use it on my Ram, especially for this trip. Is there a video or a thorough guide on how to make the necessary changes so everything works as it should.

The guide is in the first post. There isn't a video, but everything you need to know is in the first few posts.

Well, I went for it and had the ABS recall done, and so far everything is still working as intended. I did tell them I changed the ABS module, and the paperwork notes a mismatch. Fingers crossed, but seems to be good!!

i recently purchased most of the parts to do the swap. the acc switch is currently on b.o. through fca forewarning y'all, lucky for me i have a not so pretty one to get me by for testing purposes . my local dealer friend said 9 in the country and only dealers have them. but can someone shed some light on the semi auto park? i know you need a new harness and valances after reading the 68 pages. i did not see a definitive answer on if you need 4 new park sensors for the rear or if the ones i have now will work. i ran a vin from a truck with the semi park/ fca/acc/lka and came up with part numbers 68404408ab and 68404409ab for the valences and 6860453ad for the harness. i checked the sensors and all 4 show to be different then my 2020 BH with factory front and rear park sensors w/ rear park sense. my vin is 1C6RREBT3LN128815.i ordered a used abs module from lkq that is due in later today supposedly from vin: 1c6srfjt0kn787071 and a used dasm from vin: 1C6SRFU95NN227812 due in hope fully the next day or two. lets see if lkq has them inventoried correctly. new trims and bracket for dealer, i ran the vin from the abs module and it shows the same part number for my factory BH rearview mirror so i believe i should be good on that as long its not a catalog error. I upgraded to UC5 on my truck a while back so i have a used screen coming for that not due until after Christmas. the last piece to the puzzle is the windshield and the install. cheapest i have found is safelite running at about 435 installed. list on a new one from the dealer is 1125.00 /part number 68275585ag part number pulled from same vin as abs module.

There isn't a definite answer on needing to replace the sensors. But you do need the outboard sensors in the rear. My posts tells you what you need.

okay thank you. for future reference part number for valance pieces
the number with the CH's is the aftermarket part number for those on a budget.
single exhaust: 68404394aa and 68404395aa (ch1147112/ch1146112)
dual exhaust: 68404392ab and 68404393ab (ch1147108/ch1146108)
park sensor: 6mk25tzzaa
harness: 68360453ad

So in the end it took a while but everything works as it should ... thank you very much for your help once again

How did you get it to show up?

Looks like you are at the same stage as
Me, got a used dasm and jimmy making me a harness, I want to assume that the high beam and rain sensor I currently have on my truck will attach the same to the new windshield, lucky for me when I upgraded to uc5 the lane on off button was installed. I think I will get the dasm pre cabled then get windshield replaced then work on trying to figure out the abs modules. Does your truck have high beam and rain sensor already installed

The rain sensor and high beam sensor are 2 different modules. The rain sensor will work no matter what windshield. The high beam will be replaced with the DASM. Your current high beam sensor is attached to your mirror. It will be removed when you put on the new mirror. Then the camera in the DASM will be used for high beams.
