Hey guys, I want to install a Viper 3201V in my 2003 Trailblazer LT.

I was told I would need a GMDLBP module and a GM-9 T-harness.

Is this info right?

Thanks!

The T harnes is NOT neccesary, it simply makes the install easier..... The bypass module IS needed. This will REALLY help ease the install. Read the manual on this piece....it does a ton of features.

Not if you buy the bypass piece it does it for you.

You will connect the door trigger input on the alarm, to the door trigger wire on the bypass....this will (the bypass) give the alarm the trigger signal.
