Installed aftermarket HU and now I have an SES light on

[AddictionG35]

So I'm finished and got it all installed now, but I need help again. I someone to tell me a few things that you can think of that I may have done wrong. Everything is working and I even grounded the park sensor so that I can watch movies and I wonder if that may be the problem, but my Service Engine Soon light is on and I can't get it to go out, I even reset the ECU and no dice. What do you think could cause this?

can you take some pics?

Well, I had the SES diagnosed at Auto Zone, some how I had an "Fuel/Air Monitor Sensor" code, he reset it and I took a drive into SC, just got lost. Put about 100 miles on it and no SES so I don't know. I would love to take pics, but I can't find the charger to my Digital Cam, as soon as I do though I will take some pics of the install. Unless you wanted pics of something in particular.

did u pull out the stock HU??? did u also turn the car on while u had the HU out? if so then that might have caused it when i put in my HU i got and SRS light. it might have something to do with it. but i could be wrong just a thought though.
