2005 Jeep Wrangler unlimited rubicon (LJ)
So I just received my Youcanic today, however upon attempting to use it on my Jeep it says I had to have a Dodge Chrysler 12/8 pin adapter, so I just purchased it. But I’m still confused if the OBD2 plugs in why does it require a different adapter, are the pins located differently so that the Youcanic has to have them in a specific order? I guess I’m not that savvy with using one of these yet. Any advice would be much appreciated.

For Fiat/Chrysler/Dodge (FCA) vehicles from 2018 onwards, you'll require the 12+8 adapter to access bidirectional functions and clear codes. However, for 2005 models, you should be able to read, clear codes, and access bidirectional functions without any issues. Have you attempted to connect to any of the control units? Are you able to read and clear codes or view live data? Start with these steps. For your car's model year, there shouldn't be a need for any specialized adapters.
