I am getting ready to install a Sirius Unit in the 987. I will be using a direct wired FM modulator, which requires FM antenna in and FM antenna out connections of the Motorola type. I know that the FM antenna connection in the 987 is not the "standard" Motorola type. In searching this site and some others, I have concluded that this is the correct type:

or this one from Crutchfield (would need the matching plug as well):

Can anybody who has done a satellite system in the 987 (or another aftermarket install) confirm that this is correct? For some reason, none of the websites positively identify these connectors as the correct ones for 2005+ Boxsters (or any pcar for that matter).
