[Motorola] Powering a Astro_Spectra?

[w7trh at comcast.net]

Hello Folks 



Perhaps I am missing something? Attempting to power up a Astro_Spectra dash mount [T99DX+086_ASTRO]   ID# D04KKF9PW4AN. (1 Meg) 

Nothing happens.............! Is there a ign. sense wire that plugs into the "Sub D" receptacle? (I am used to the Maxtrac/Radius that use the same power cable, and power on without a sense line.) 



Please forgive my ignorance, as I am just getting into the "Astro_Spectra" arena. 



Thank you!
