You can get by with your led blinking when the car is off, because essentially that is when your alarm would be armed. Well, take another look at that wire and see if it gives you a ground signal when you activate the dwa. 900ma is more than we need to drive a relay. When you are testing the red/black wire, are you using a multimeter or test light/probe? Is the signal constant or a pulse. You need to use something that lights up red or green, letting you know if the signal is positive or negative. I mean, you could use the multimeter if you have nothing else. Just let me know and I will tell you how to test for it properly.
