[da1stprince]

no video. Just buy oem front fenders, hood, bumper, from Tesla. and Custom fit the rest. some cuting crash bar, make custom bracket for the front grill & headlights and wiring repins for the fog lights.

how did you get these parts? Tesla refused to sell me that year bumper

no, work around the oem system. this is why not many people can get it done.
i cut alot of stuff and make alot of modification to fit the bumper.

oh no, that diagram is for older model s to new model x foglight.. ONLY
older model x wire diagram is this. try to match to new model x ( i have no expence with)

The old model X and refresh used the same foglight plug beside old X have double ground compared to the refresh 1. When plug in, foglight stay on abd connot be turn off inside also there's no turn signal.
I've tries your diagram Hotboy408, and also every combinations beside the ground switch all over the places, nothing work and now I don't have my car amber turn signal and no blinking noise inside the screen. My foglight main control screen stop highlighting the foglight for me to turn on/off. Beside all that problems, when clicking the turn signal left or right, the rear and side marker blinking very fast. Now this doesn't look good.

Did anyone try retrofitting the refreshed 2021 Model S bumper on previous year models?
I need to get the front bumper on my 2017 model S replaced due to the damage. Checking if the new bumper can work as replacement

While I can't provide you with the 2021 Model S bumper, I can suggest an alternative that might interest you.

you should check the pin #5 is lin communication wire . if you plug it in. you actually short it to ground .

the turn signal doen't flash or make noise because there's no feedback of led bulb. aka open connection
you need to put pin #2 (older) to pin #4. (newer)

looks like the rest of the wire is lin-com line, so it won't work with newer light.

since older model x use lin-com.. you can't use the front harness.. i recommend check rear tailight for the source signal

here the diagram. tailgate diagram specific label.

Thanks, I will try that next.

But i know for sure even without the front fog light or turn signal on, my cluster of the car still show the blinking signal and noise and the main unit highlight the fog switch before this happens.
Like you said I might short somewhere and how foglight disable in grey and no blink and noise on signal.

Do you have a clue where I shorted? I looks everywhere for a fuse or relay everywhere to replace it with no luck

 

[Hotboy408]

if you short communication lin. alot of things can happen.
try to start over, plug everything back to factory and reset your car.

I haven't touch my car for 2 weeks. Been busy lately.
It suck that MX is not as easy as MS by moving somel pins. I was waiting if someone might figure it out. Hate to tear up the both old and new fogs and then one day someone got it to work.

Don't they have a fuse for protection on communication lin? Btw, the car ride and work normal. My high beam somehow able to select again even without the foglight. With all those pins rearranging back and forth I might shorted both old and refresh foglights for me to test it. Like you said there's no foglight led feedback for the car to show blinking in cluster or turn signal noise.
I feel like it's a wast of time and money because of the LIN communication of the foglight.

My bumper got damaged in an accident and the body shop said there is a new autopilot sensor inside the 2021 bumper and because its a safety feature, it cannot be put on my 2018 model S.
