dude, unwire what you have done, unplug the battery and let it reset for 20 min. plug the battery back in. that SHOULD take care of the dtc going awall.
you cant wire it in with the fuse panels. as far as i noticed, you can only do it with the wipers, BUT, you will still have a huge draw, especially doing 2 windows at once. honestly, its not worth the pain to add these kits, they never work right and not only that, it gives the car a major chance to f up!
if you dont want to or cant take the kit back, try wiring it to the battery directly with a fuse on that line. its not the best way, may still void your warrenty. but alot better then having your car go nuts. what happened was when you wired it in, it must have jumped and shorted into the system. when i wired my stereo dtc kit, i did the same thing. no one know how i did it, but the same thing happened. either which case the dtc isnt to be messed with, it has the air bag, power stearing, dtc, stereo and air bags all bundeled intogether. also if i remember the wiper is only a 10 or 15 amp draw which automaticly puts you well above.
