The Evo X comes pre-wired for nav even if you do not get nav. Meaning it has an extra plug that is used for the OEM nav unit if you went that route. I'm guessing that this extra plug has the usual nav required wires like parking brake, reverse, speed sensor etc. Correct assumption?

I am installing an after-market nav unit, Eclipse AVN726E. It does not require speed sensor so I just need to figure out where to connect the parking brake and reverse wires.

A last resort is to run wires to the center console for parking brake and possibly fuse box or trunk for reverse. But I'm really hoping/praying that it's possible to tap into the OEM pre-wired nav plug for these wires.

Does anybody know which color wires from the OEM nav plug are for reverse and parking?
