I have a premade relay that came with my compustar alarm. I have the relay wired up like the "Normally Closed Starter Kill Relay" diagram found on this site. This is for a 95' gmc sierra. The truck will start if the alarm is disarmed but not armed. Do I need a different type of relay for this make/model? I know the doors required a special relay to work properly. Also, there is a secondary starter relay that came with the alarm that I have not used. Am I supposed to use this? If so, how? Thanks

For got to mention that this secondary relay can be used for a 2nd ignition. Is this necessary?

Is this a remote start alarm or just a alarm? What model is the brain? ------------- Top Secret, I can tell you but then my wife will kill me.

Sorry...when I say "start" I am refering to remote starting the truck.

So it is a remote start alarm, what model# is the brain? It sounds like you have the start wire (green IIRC) on the wrong side of the starter kill relay. If it is on the key side of the prewired starter kill relay, when the alam is armed, it will not allow the vehicle to start. Move it to the vehicle side of the relay. Always post as much info on the vehicle as possible. Without knowing the vehicle and the exact model # of the unit, it is a guess at best to what the issue is and if you do indeed need to use the 2nd ignition etc. ------------- Top Secret, I can tell you but then my wife will kill me.

Dude, I have twice asked for the model# of the brain although now I am going to assume it is the CM3000. I have asked once for the vehicle this is going into. YOU MUST ANSWER THESE QUESTIONS. Right now it sounds like you have the starter wire (green) on the wrong side of the starter kill relay. Now if say this is in a GM pickup and you do not do the 2nd ignition line, you will cause a failure of the transmission and a huge repair bill. So when questions are asked, please answer them so that a proper response can be given. ------------- Top Secret, I can tell you but then my wife will kill me.

The starter wire in the ignition harness is Yellow. There is a starter wire(yellow) & starter kill wire (purple) coming from the alarm. I have yellow on the ignition side & purple on the starter side (Followed the relay diagram mentioned above). When you say start wire, are you refering to the starter output wire? Currently, its on the starter side of the relay.

2nd ignition is a must. It still sounds like the starter wire from the brain is on the wrong side of the relay for some reason. Wire in the second ignition line and retest. Good thing you posted about the vehicle, that minor slip up just saved you a $1500 repair bill on a new transmission (no kidding here either). Some GM vehicles also require a 3rd ignition. Once you get this thing running, remote start it, take it for a drive and pay close attention to how the tranny shifts. If it is not shifting properly, turn it off and start it with the key. It should shift fine again. That is a indication that another circuit needs to be powered up from the remote start brain.

I'll switch the relay sides but could the relay just be bad?

Yes it could be. ------------- Top Secret, I can tell you but then my wife will kill me.

Also, the 2nd relay has a purple wire, blue wire & red wire (in 2 places on the relay). The purple & blue are supposed to attached to the pink/white wire on the ignition harness. How do I wire this up?

I found this (this matches the way the relay is setup. I changed the 30 colors to match mine): 85: 2nd ignition output wire from brain86 & 87 : 12 volt constant fused at 30 amps 30 : pink/white wire on Truck 87a: NOT USEDThere is not a 2nd ignition output wire coming from the brain, so what do I do with this wire?

Update: I switched the starter wires around and its working now. I also wired up the second ignition. I wired 85 up to the 1st ignition wire from the ignition harness. Everything seems to be working except the fact that the Secondary ignition accessories are now always on. Am I supposed to wire this somewhere else and not to the 1st ignition wire?

I removed power from 86 and not the secondary ignition does not stay on. However, I don't seem them come on until the key is in the on position. Is the correct? Can I get some help with this?
Thanks!

The 2nd ignition relay was already prewired on this brain, all that needed to be done was to toggle the relay with the appropriate wire. If I were you I would stop now and take it to a shop and have it finished up to ensure safe operation of your vehicle. ------------- Top Secret, I can tell you but then my wife will kill me.

No one works on compustar alarms in my area. No one will touch it. I'm on my own here.
The 2nd relay is prewired to the brain. I installed the relay like I mentioned above but it was supplying constant power to the accessories. I don't believe this is normal. I'm stuck with doing this on my own. I guess since no one can tell me how to wire this relay I'm just gonna have to experiment.
Thanks anyways...
