I just installed a kenwood ddx-514 deck into my car, only one of the 2 plugs that went into the stock stereo deck goes in, ever since I installed it the A/C no longer turns on, I believe it is from the other plugin, any ideas on how to fix this? Also the antenna plugin on the deck will not work with the stock setup, anybody know of any adapters or any ideas on how to rewire this etc?
any help on both questions would be greatly appreciated.
