PMP450i AUX sync for PTP450BH

I would like to use the GPS AUX sync on my PMP450i for my PTP450BH is this possible and if so what would the cable pinout be since I need to go from a RJ45 to RJ12.  I have searched and I have had no luck finding results.

Hello, this post should show you the necessary pinouts.

And this post may help for remote applications in the future.
