2003 tahoe with 791rs & 457gw

Okay... first of all, hi everybody!

I started using the 457gw last summer wid viper rs 160, 771 an 791, at least once a week.  Never heard any complaints from customers... seemed everything works for them.  Then I get an 03 tahoe and think "no problem" done a lot of em, right? WRONG!!! 

first, the heated seat thing (read that-makes sense)  but then, the perimeter lighting and the lock/unlock wouldn't work.  Disarm would chirp but no unlock, arm would chirp but no lock.  It seemed to stop messing up except for the perimeter lights, so i left it alone.  Now, the locks only work with the factory remote and if u try to remote start it, the factory alarm goes off.  WTF?  Can anyone explain this?  I've done the exact same install on 02-05 tahoes, 03 silverado ss, 03-04 escalades, you get the picture...and NOW it messes up in MY own friggin car?!

Anyone have any input?  it's been installed for about 2 months and worked fine til now.

nope...  i just followed the directions in the box.

so i put a diode on the ground wire and reset the bypass.  everything seems okay for now.  if it happens again, should i just exchange the bypass?

thanks for your info
