Adding safety options ie lane assist types

GS-21AT4 · June 13, 2021

Has anyone ever added safety packages after they already own it. I would really like to have lane departure and front and rear notifications. I understand my mirrors would be need to change. For blindspot but I don't need or want. Just thought the front and rear notifications would help in a busy parking lot. Just asking I just got the truck

thanks in advance

you need front windsheild cam for lane departure, lane keep, auto beams and adaptive cruise. Hardware would be windsheild camera, windsheild, headliner harness, dash harness and switches. Then for everything to work right you need programming if it can be done. Rear cross traffic alerts is controlled by sensors in bumper step and I think that can be done. front and rear park assist are the 4 circles on front and rear bumper there is a module that controls.

Thanks for the quick response. That helps a great deal. Ahh, Then I will go look at aftermarket or leave it alone. Just got it and already looking to upgrade it LOL

Thanks again

i got addicted to upgrading. i added oem memory seat, power fold, cooled seats, heated rear seats, 360 vision, high country cluster, hud, video rear view mirror and power up down tailgate. i already had cross traffic and park assist. i may try some day to see if it is possible to add windsheild cam i have some parts i am guessing some things will work partially but some custom programming will be needed if possible.

...you have to have decent chunk spent in doing all that, why not just buy an LTZ?. just curious

buying used parts to upgrade is cheaper than buying an ltz or hc. had fun doing it. dont like chrome. wanted white, hc only comes in pearl.

That would be fun. I will be looking into it. As for why I didn't get chevy is that they don't offer power passenger seats in any of their trucks so went with a GMC but ordered one but came in with less options then I wanted. So after waiting for a month for delivery. I took what they had to offer. It sucks trying to find and buy a new truck in today's market.

I have a 2021 Sierra Elevation. Is it possible to add memory seats to that truck? I also have the ior radio but want wireless Apple CarPlay. Do you know if that’s possible? Thanks

with ior radio probably not possible to add oem wireless carplay. here is memory seats check your harness under seat to see if your body harness has all the pins if it does it will probably work doing what i did.

Where exactly would I check? there are two connectors going to the motors and two connectors going to the adjustment switches other than that the airbag connector...

Would love a detailed write up on adding this! I really wish I had the sunroof and around view option.

if someone can get me a part number on headliner harness from a T1 crew truck with windsheild cam i might consider trying. the headliner harness plugs in under glove box. there arent any at dealership for me to look at.

you need to check where seat harness connects to body harness. take side trim sheild off seat track and you should see that big connector.

The Lane assist Camera 84586312

The Headliner harness 84711898

not sure if that's the right harness, there are only two listed, one with vanity mirror and one without

I did and I cross referenced the pins to the GM electrical body builder guide and it seems to have all of the pins there.

I'm also wondering if I could just change the seat harness to the memory seat harness, I have power drivers seat and all leather already so I don't want to buy the whole seat...

The PN for the seat harness: 84513012 (With power, Without ventilated, With memory, Without haptic alert)

If I could just switch out that harness and add the memory module and buttons and such it would be way cheaper and easier.
