08 cobalt headunit

here is the issue I am facing, when the guy turns on his signal lights and goes to turn the wheel the power to the deck dies, I know I wired it according to the diagram so anyone else have this issue? I wired in an alpine headunit with an ipod adapter and used the metra gmos-lan-03 adapter harness. 

 

Here is what I wired in according to the harness diagram;Adapter                                                          Deck12V Ignition / Acc. . . . . . . . . . Red wire wired to ign acc for deck12V Batt / Memory. . . . . . . . . Yellow wired to power for deckGround. . . . . . . . . . . . . . . . . . Black* wired to groundPower Antenna. . . . . . . . . . . . Blue ** capped this wire not needed***Amp Turn-On . . . . . . . . . . . . . Blue / White *** I capped this wire and just ran the remote wire from the deck harness to the amps*Illumination . . . . . . . . . . . . . . Orange ** wired to the illumination for the deck harness***SWC GREEN/ wite............... ** capped not required for this deck***All speaker wires are wired directly to the deck's harness and are functioning as they should Colour codes all matched up.

So I am left with 2 possibilites, 1 the gm module is killin my deck power or 2 Something got pinched when I wired the deck and pushed it all into the dash. Memory for radio channels etc is retained when the deck power dies by the way.

ok I took it apart in hopes of finding an issue and I noticed that it was not the gmos-lan-03 adapter but a pac adapter the c2r-gm11 adapter, so I used a buss add a fuse and ran a wire from the fuse panel to the deck for ign acc wire. The wiring diagram for it had a wire for ign acc but it was 1 amp max for it. Either way it works just dandy now and he is a happy customer.
