I'm thinking my starter wire isn't getting any power because when I connect the violet H3/4 starter wire to my power probe and give it 12 volts of power the car will start.
I've tried connecting H3/9 to both white and straight to a 12V and it still doesn't work. So now what?

See I can get you right. When the starter wire (red) is cut, you connected the key side of the red wire to H3/5 - green and the car side of the red wire to H3/4 - violet.      Here are some Q's I need you answered first .

  • When the alarm is armed, can you start the car with the key ?
  • when the alarm is disarmed, can you start the car with the key ?

With the starter wire cut and connected to H3/5 and H3/4 I cannot start the car no matter what.
With the starter wire uncut I could start the car while both armed and disarmed.

Either you had loose connections or the N.C. contact between H3/4 & H3/5 is faulty. To check the starter kill contact, pull the 10-pin harness out & put a meter on two terminals on the brain side. If it has no continuity when it is disarmed then you will know the answer.

Alright well I still haven't gotten my multi meter back from my brother so I will have to wait to check.
So whiles it's disarmed it should have continuity but when it's armed it shouldn't, correct?
And if the contact between the two are faulty then what are my options?
I need the starter wires wired up correctly for my remote start to work, yes?

That is CORRECT

Replace the module or just connect the violet to the red starter wire without cutting it. Then you have no starter-kill.

That is an understatement.

Well I just checked the continuity and here are the results.
Armed: 0.0
Disarmed: 0.0
So, I'm screwed for a starter kill?
And when you said it's an understatement did you mean it's possible to still get remote start to work? How so? My main goal is for remote start to work not for my starter kill.

No you can still use it without the starter kill OR use an external relay like this.
Ignore the unit's green wire.
Take a relay and 3 x 1N4004 diode.
Orange GWA output AND blue status a.k.a. GWA wire to 85.
Ignition wire from car to 86.
Break starter wire, key side to 87a, starter side to 30.
Starter output from Viper to 87.
The diode joins 85 to 86 with its band towards 86.
Also inline diode both wires to 85 before you join them, diode bands towards Viper.
This will give you starter kill and R/S with alarm on OR off.

Ok thanks Howie, I don't really want an external relay and starter kill doesn't really help me since my car can always be push started. So I'll just leave it out. Thanks for all the help.

Ok Howie or moonliter, turns out my starter wire connections are okay, any idea why right when I connect my ignition 1 I lose the ability to start my car?
