The modules from aftermarket manufacturers in China may not use semiconductors which comply with more stringent automotive quality fabrication standards. May work upon installation, but for how long? That's the big question.There are several companies that sell the usb module with the data port. From what I hear, they all seem to be working fine so it doesn't seem necessary to get the OEM part for this. I'm using the Tparts module and haven't had any issues.
Does not make any sense to me. I would ignore the app message you got and visit the Service Center in person. Tell them you are here to pick up you ordered part. If they again decline to sell the part, ask them why Tesla...My service center in Devon is saying the USB hub is a Tesla only installed part - so they want ~$40 for labor install which is ridiculous. Trying to convince them that I can self install, but not having luck. May just go 3rd party at this point since the part is now $90.
You had mentioned that before but is there any evidence that these aftermarket parts are bad for the car? Everyone plugs a bunch of aftermarket parts into their cars that are made from china: cheap usb drives, game controllers, usb hubs, etc and I've never heard of any problems stemming from this. In fact, if you look at the Tesla OEM module, doesn't it say "Made in China" on it?The modules from aftermarket manufacturers in China may not use semiconductors which comply with more stringent automotive quality fabrication standards.

Tesla warrants parts and labor on all new cars, so they will specify necessary specifications for any part suppliers to ensure parts meet their quality standards.You had mentioned that before but is there any evidence that these aftermarket parts are bad for the car?

Also, Tesla's parts catalog does show that their OEM module with data is a Tesla only part. It's not listed as OTC so they may not be selling it OTC anymore and require the work to be done by Tesla service.
Love this community. This is awesome. I've always yearned for the 2021+ console, but the TESBROS fella made it sound like it'd be hard to achieve. I've got the 2018 Model, early-ish VIN. Imo, this really updates the interior to a more premium look. I'll be trying this hopefully in the summer (temps are too low for me to be working on the car up here). I messaged Honha requesting the exact same parts. My question is. Where to the adapter's plug into on the new console? I haven't ordered one but I guess it might be obvious once I have it. The OBD II version is interesting though. Does that plug into a connector on the console? Or is it for a connector under the rear console? Trying to understand it's purpose. Thanks!I had these 20-pin to 26-pin adapters made. One is with an OBDII diagnostic plug, the other one is without the diagnostic plug. Cost for both was $30 USD with free shipping, plus taxes. They were just shipped today from China, so should be delivered in about two to three weeks.

I sent the company that made these, the pinout diagram below, along with a rendering of what I wanted. I prepared the pinout diagram based on the Tesla Wiring diagrams. The company didn't have on hand all wires in the colors I prescribed, but only had to substitute for two colors.

They said they used the "original connector housings" (what ever that means?), but if I ordered more, they could match all the wire colors I had requested and they also could substitute less expensive connector housings, which would reduce the cost. I'm not likely to buy any to resell. But if anyone is interested in purchasing these for their Pre Jan 2019 Model 3, contact the company directly with the messaging center on AliExpress.com.
The company (Honha Autoparts Group Co., Limited) sells on AliExpress.com under store name Honha Wire Harness Company Store. They sell automotive harness repair supplies, but also Tesla Model 3 OBDII diagnostic plug adapters.
kayrish,
For your 2018, the 20-pin to 26-pin adapter plugs into the 26-pin connector from the 2.0 Center Console's wire harness located after removing the lower rear trim cover. The other side of the adapter plugs into the cars wiring harness (20-pin connector) at the same location.
The OBDII 20/26 pin adapter is optional. You may not find the OBDII data useful. The OBDII connector is for connecting a wireless CANBUS adapter; used most commonly with the "Scan My Tesla" App for Google Android or iOS smart phone/tablet, usually operated in Airplane Mode (no data connectivity required).
There were already OBDII adapters available for early builds (20-pin) and also OBDII adapters for later builds (26-pin). You could plug one of these (type 20-pin or type 26-pin) into either side of the Honha non-OBDII 20-pin by 26-pin adapters, but you'd have a large bundle of excess wires to deal with.
I didn’t bother to do this but I also read somewhere that someone was able to do this. If I remember correctly they just had to contact Tesla and request it.Has anyone bothered trying to get Tesla to change the console type on the car? What I mean is - when you use the app, e.g. the climate screen, you see a top down view of the interior of the car. I'd quite like to be able to get them to change the actual console visual to the correct one.
I'm sure I read somewhere that someone had done this, but I can't find it and don't really know how to articulate the request when I speak to Tesla.
There’s no way it’s that easy (switches to tesla app and messages service) lol but that would be awesome!I didn’t bother to do this but I also read somewhere that someone was able to do this. If I remember correctly they just had to contact Tesla and request it.
I wouldn’t be surprised if they say no with their usual response being there is no official retrofit so they won’t change any car settings.
Not a good idea. Only Fremont built cars after October 4, 2020 have pin #6 ( Inductive Charger LIN ) of the 26-pin connector populated. If in the future, Tesla implements Inductive Charger Controls in firmware, the User Interface on the Center Display would likely show data communication errors.Has anyone bothered trying to get Tesla to change the console type on the car?
