I am installing a Viper 550 ESP in a 98 Blazer and I need help on the door triggers. Do I need to diode isolate the 3 door triggers or can I just tap into all 3 with the negative door trigger? And is there a diagram for doing a diode isolate if they need to be.

Thanks, freezing in fargo

You should be able to get the one wire for the two doors and hatch. You will have to program the alarm for delayed courtesy light.

So I use the Dome light wire at the BCM is this correct? That will trigger all 4 doors and the hatch?
