You should also mention that the dash endcaps just pops out. It makes running the wire a LOT easier.
If your detector stays on, check on it after about 30 minutes. Many times it'll power down once the car goes into sleep mode. You'll hear it power up again when you unlock the door, or open the door if it's not locked.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
