I have a 2004 crossfire base with infinity system( subs behind the seats) I purchased this model head unit with a 70-1786 adapter.. Where should I tie in the remote and aux lines to the adapter harness? There is also one for parking break but I think I just cap that one? Thanks for any assistance.

The model number is in top left corner beginning with DV

 

***UPDATE***
I was able to get all features working it seems by scanning forum another time (5th). Now I just need to figure out why back subs aren’t working, they weren’t working when I acquired the vehicle either.

 

Have you inspected them to be sure the cones aren't worn out? They are rebuildable.

 

I have not, but if my theory is correct the amp wire I tied into the headunit with that adapter powers the speakers as well, therefore it’s narrowed down to the subs being bad or wiring from amp to sub?
