Thanks I mean which wire from the relay should I wire that to.

u have to wire up ur own relay to the small purple wire in the 4 pin poug near the ribbon cable on the relay pack. but in response to the other guy, yes the brake wire chould set the alarm off. have u learned the tach wire or maybe set it to voltage sensing. without one it wont work also!chuck

Cool Thanks =) What should I wire up to the relay? Do I also need a high current positive wire?

have you check you tach wire ? are you using voltage sense ?

Yep I checked the tach wire and its set to the default, tach sensing.

Does your remote start unit have 2 ignition and 2 start outputs?  If not does it have 2 of either?  If it does not have 2 of either, you will have to make the ignition wire trip 2 relays so they power the 2 wires listed for ignition.  Same if you only have one start output.  You should always use a high current source when installing a remote start.  It has to power the AC, heat or anything that comes on when the vehicle is remote started. 

When you ask what should I wire up to the relay?  Which of the 4 wires (2 ign and 2 start) do you not have connected?

It has 2 ignition and 1 stater output. Right now I don't have the 2nd starter connected.

Which of the 2 starter wires do you not have connected? What color is the starter wire coming from the alarm brain?

I connected the purple (output to starter circuit) to the 1st starter on the car. I'm not planning to use the anti-grind/ starter kill function.

I will draw you a diagram this evening. But if you want to dive in today, all you need to do is remove the purple wire of your alarm from the wire that it is now connected to. Now connect the purple wire to terminal 86 of 2 relays. Ground terminal 85 of both relays. Connect 30 of both relays to a constant 12 volt source via a fuse at the point of connection to said 12 volt source. Terminal 87 of one relay goes to the wire that you removed the purple wire from earlier. Terminal 87 of the other relay goes to the other start wire.
