Using Arduino code
How do I use the provided Arduino code to connect the software to a '95 Wrangler YJ over the SCI bus? The car only has a 6-pin Data Link connector. I would like to read the error codes from the PCM.
Here is a solution for you while they get back to this great project:

You will need an inverting buffer chip in the RX/TX lines because OBD1 controllers use inverted UART logic. As far as I know Kate's software does not support OBD1 controllers.
Okay, thank you very much! I will try it out as soon as I get the parts to invert the signals.
You might be able to get away with using SoftwareSerial which should drop in and supports inverted logic.
Hi! Very nice to see interest still popping up for this project.
To answer your question, another set of libraries other than this one is probably what you want. In a really early commit to this repository, the Arduino code was much friendlier to use with an Arduino IDE terminal but this current version was meant to have my C# application talking to it. I was working on porting the embedded code over to C anyway so I'm not sure if it even works.
