I can't find my diagnostic port to install my gear indicator on my 2005 600. Would help alot knowing my gear with a glance and remove 1 more thing I have to think about. Can I get some help?

 

[what?]

But, it adds one more thing to look at?

Don't worry about the number of the gear, just make sure your RPMs are where they need to be. Some people ask "what gear are you in when.....". The answer is "the right one". Number is irrelevant.

The diagnostic port is under the drivers seat, behind the fuse box.
