First experience with a 457g

So I finally got a gm that I could try out the 457g.  It was a 2006 Trailblazer.  Couldn't find any info on it so pulled up an 05 checked all the wiring seemed the same.  After reading and hearing some horror stories about the 457.  I called up Dei , and they said the 457g would work.  So I proceed with the install.  Got everything wired up plugged the 457 in got it to program and everything.  I must say went very smoothly.  Much better than selling the customer a 456g for the locks and a 555l for passlock.  On a side note the 457g will not reengage the factory alarm after the r/s shuts down unless you tie the factory alarm rearm to the lock input of the 457.  I know may sound obvious, but I just want to put it out there.Cause I'm So white and nerdy...

The biggest issue i've seen with the 457G is on Trailblazers. At least 50% of the ones i do won't lock the back hatch after it unlocks. Mike M2
