I purchased a used USA SPEC PA15-ACUxl on eBay it works 100% says seller or money back so it doesn't come with cables just the box so basically what I need is vehicle harness is this the one http://www.ebay.com/itm/311085569363?redirect=mobile please correct me of I'm wrong and what else do I need to plug it in rear trunk through xm box. Thanks for the help!

 

Or will this one work? http://www.bernardiparts.com/Honda-2-Port-Audio-Sub-Harness-most-models__08A31-0F1-000.aspx

 

just so I am clear... you think that "Y" cable replaces this cable?



And do you have the ipod side cable?

 

I don't need the iPod cable since I just want it to plug my phone through 3.5mm audio jack I have an rca aux cable already I just need the y harness that plugs into xm box in rear of our trunk I keep seeing 21 pin connector and 14 pin I don't know what cable I need.

 

I went ahead and purchased this to connect USA spec Pac15 Acuxl to rear xm box on my 2006 Acura rl. Please tell me this is the correct one! http://m.ebay.com/itm/311085569363?txnId=574438287021

 

I get that it will pick up the nav harness... I just dont understand how that cable you keep posting will hook into the pin out of the USA-spec...
