Need help regarding Sirius install

[Harvey Halabookie]

I bought the Clarion Calypso tuner with the car installation kit. I have figured everything out except one thing. I want to hardwire the tuner to the factory head unit (I don't want to use the FM modulator).

My truck has the Bose system, no XM, and no CD changer.

 

Where should I tap into the HU for the auxiliary input from the Sirius tuner? Are there RCA-type inputs or just a pin connection?

 

Thanks in advance!
