12+8 Pin Connector to OBD2 Adapter Security Bypass Cable for SGW-Equipped FCA Vehicles for Diagnostics, Coding and Programming, Compatible with JScan App

High quality works great on jeeps and Chryslers who don't have standard OBD2 ports

Worked great on my Ram Promaster 1500 2021

I used this adapter with the JScan app to recalibrate my Jeep JL’s speedometer after upgrading to larger tires and adding a lift kit, and it worked flawlessly. It connected to my OBD reader with no issues, synced with the app right away, and let me adjust the speedometer accurately on the first try. No random disconnects, no errors, and the changes saved exactly the way they were supposed to. If you’ve changed tire size, gearing, or suspension height and need a reliable way to dial your speedometer back in, this adapter is solid.

worked perfect using Jscan on my gladiator.

I was skeptical about buying this bypass because there are SWG Bypass products costing over twice as much. I used this on my 2020 Giulia to perform routine maintenance and reset the service interval. While this isn't the only product you'll need it is a requirement to be able to write to the ECU in newer Stellantis vehicles (Afla, Fiat, Chrysler, Jeep, Dodge, etc). Installation wasn't difficult but it wasn't the easiest thing either. You can't mess it up, it only installs one way, but access is a pain. The SGW on a Giulia is behind the lower dash next to the steering column. You can get a single hand into the space without disassembling anything but the wire connectors you'll need to unplug from the SGW are hit or miss as far as the release clips are concerned and you can't see what you're doing. You have to do everything by feel. One came right off, the other took 10-15 minutes of fiddling with a paper clip to get the second clip released. I HIGHLY recommend getting an extension harness for your SGW so you will only ever have to perform that task once. It's not pleasant! Where this device differs from some of the more expensive bypass units is that this one replaces your OBDII port while it's plugged in. In addition to this product, I also needed to purchase an ELM327 adaptor to connect the car to my laptop. For simple tasks, such as resetting the oil change interval, no other adaptors are needed.

This unit looks great and works, but I had to do a lot of research to find out where it plugs into the system on my truck. A lot more information on how to install the unit and what programs you need would be helpful.

Me gusto. Cumple lo que promete. Buena calidad

Hace muy poco que lo adquirí, pero veo que está hecho de muy buenos materiales y funciona perfectamente.

boa qualidade

m'a permis de dériver la prise OBD et le boitier SGW de ma Fiat 500 X pour pouvoir utiliser mon appareil de diagnostiques.

FCA系にて必要とのことで、仕事で試してみました。（人柱的に） 結果からいきますとマセラティで診断消込等できました。 ただ、SGWモジュールを探す時間の方がかかる可能性はあります。 持っていても良いパーツと思います。

Owning a Jeep, I use this a lot. Works perfectly!

Works perfect and easy to use Works great and easy to use.
