So, I just installed sequential taillights on my 05 in November. Now just this last week after I drive the car and go to set the factory alarm, the lights dont flash, but the horn honks as if it is set. Then a few minutes later the alarm goes off.

Now, if I don't set it and just lock the doors...I can go out a few minutes later and set the alarm and it works fine. The odd thing about this is that it is very inconsistent. Has anyone ever heard if this?

And sorry...I thought I posted in the general forums. Not the V8 section.
Thanks
