Good for 2004 Harley XL 1200 custom

This cable does exactly what it claims to do. It allows you to bypass the SGW. Only complaint I have is that the cables on the car are difficult to reach and disconnect. This is not the fault of this cable of course, it is Jeep's design, but be forewarned that it could be difficult to access.On the 2021 Jeep Compass, I found it easier to remove the kick panel in order to plug this cable adaptor in, as it gave much easier access to the connections. You still have to get on your back all twisted and contorted to remove the OEM connection, but once that's done, the cables have enough slack to re-route them towards the front of the car and you can then connect this adapter easily while sitting in the driver's seat. Re-connecting the OEM cables is going to be a giant pain, but I will deal with that later.Bottom line is that this adaptor works. Good luck getting to the connection.

If you want to modify certain settings with an OBD2 device and a program like jscan, alphaobd etc in your Jeep wrangler JL or Gladiator JT, you'll need this. Plugs right into the security gateway, and then you can connect your OBD2 reader to it, and connect to your software. You can then make changes like updating tire size so your speedometer will read correctly if you've changed tire sizes, or if you upgrade to LED lights you can make the change in the software so it will recognize it and not freak out. There are a ton of things you can do, but plugging directly into the OBD2 port without this module won't allow you to do much of anything. No instructions came with mine, so hopefully this picture will show where you need to plug this into. It's up and behind the stock OBD2 port, two wires need to be removed and then plugged into this device. OBD2 reader plugs into the other side. You can't really plug the ends into the wrong cables. They only fit one way.
