Onstar GPS antenna wiring question

[TahoeMedic911]

Hello all! Here my question: 2001 Tahoe LT Non Bose audio

Where does the Onstar GPS antenna wire terminate. I know it starts at the antenna to the right of the rear view mirror but from there where does it go. I have checked the onstar brain box behind the instrument cluster but the only antenna wire that connects there is the cellular one (which we all know is useless thanks to digital cell service). Any ideas?

Thanks!!

The onstar module should be behind ip and to the right of the glove compartment

Ok the one behind the ip does not have the GPS connection on it, where is the one to the right of the glove box...the only thing I see there is the PCM/ECM unit

The pcm is under your hood below the battery, not under the battery but towards the front center below the battery
