1 double pulse will be a programming feature. Read the install guide again.

2 Read this

3 You will need an aux out programed for start to trigger an extra relay for your second starter. DO NOT connect both to one output....

wire your relay like this. negative input, to posative output.

for your second starter, splice a wire into the purple wire on the ribbon harness (you'll have to seperate the wires a little), connect that wire to 85 terminal on a relay, connect 86 and 87 to a constant 12v source at the ignition harness, and 30 to your second starter.

to recap:

85 (-)starter trigger from RIBBON harness (the thin wires, not the thick ones)

86 (+) constant 12v input from ignition harness

87 same as 86

30 to 2nd starter wire.

do i have to hook up the factory disarm wire from the viper to the disarm wire in the car?also,how do i hook up the dome wire from the viper to the car?i know i have to isolate every door switch,but does anyone know all those wire colors and where i can find them in the car?seeing that the viper has anti grind,do i have to wire up a relay so that when u turn the key it wont grind for that split second?

no, on your particular vehicle there is no need to connect the disarm wire for remote start. if you use yellow for lock and yellow/red for unlock, it should disarm the factory alarm upon unlocking with a double pulse (this will be a programming feature).

Also I don't think you'll need to hook up your dome supervision either. I beleive from the factory, your truck should turn the domelight on upon unlocking. If not, just connect the BLACK/ white wire from the viper to your driver's door pin with a relay as follows:

85 to BLACK/ white from viper

86 to constant 12v source

87 to ground

30 to driver's door trigger in the truck(i think it's GREEN/ red)

you shouldn't need to wire up an anti-grind, it's built into the remote start.

As for the door pins i beleive they are as follows:

GREEN/ red for driver's door

GREEN/ black passenger door

RED / black rear doors

they should be in the vehicle's security module which is located above the hood release in the driver's kick panel area. use a multimeter to make sure that you've got the right wires. These door triggers should be (-) btw and will connect to the green (-) door trigger on the viper. remember to diode isolate them, you can do this by getting three peices of spare wire in moderate lengths, splicing into the door trigger in the vehicle, and add a diode at the end of the wire with the stripe (cathode) towards the car. repeat for all three triggers then join the anode ends of the diodes together and solder them to the green door trigger wire from the viper.
