[QUOTE="ShiningBuick, post: 7234955, member: 578641"] There's not all that much to know. Once you get your wire colors/locations it's cake... IIRC the Stratus has 4 door pin triggers, all negative. So you'll have to split the - trigger input into 4 wires, diode isolated (a diode on each, with the band facing away from the alarm brain) Then add the hood and trunk triggers in the same way. Trunk should have a trigger too, especially if it has a trunk light.. just tap into the switched side and attach to either the negative or positive trigger input depending on which type of switching it has. For the hood just add a hood pin or mercury switch and diode isolate to the negative trigger. The door locks I'm pretty sure are negative trigger... so just track the two wires down... check them w/ a mulitmeter (cont to ground when pressing lock/ unlock), and tap into those. The factory arms/ disarm wires are the same thing.. should go to ground when you turn the key in the driver's door lock cyl. The starter kill relay is easy enough.. snip the starter wire and wire it to the relay as described in the manual. Domelight wire I usually don't bother with, the trigger zones work best IMO. Add an extra siren under the dash while you're up in there. Loom and tape the wires good... hide the brain somewhere sneaky where it's super hard to find / get to. Hmm... that's all I can think of off hand. [/QUOTE]
