The car hasn't changed body styles for a few years. Wiring will be the same as 2005.

as jworm mentioned, read this post. it has wiring diagram location and colour of wire. look then ask for help if needed. As for the alarm you purchased, ultra starts are good units. have one of my moms car and it works pretty good. decent range.

Those wires are clearly indicated in the first post I referenced. Here, let me copy and paste them for you:
Tachometer pink to RED / white ac ECM, 34 pin plug, pin 23 or cluster
Notes: The ECM is behind the glove box.
Can also go to a fuel injector under the hood and use the wire that is NOT blue/black (4 cyl), red (4 cyl turbo), or yellow/blue (6 cyl).
Parking Brake gray - sw or driver kick, harness to rear
Factory Alarm Arm brown - dr kick or BIU, 35 pin plug, pin 3
Factory Alarm Disarm yellow/red - dr kick or BIU, 35 pin plug, pin 12
Notes: The BIU (Body Integrated Unit) is to the right of the steering column.

The unit is for manual trans As for wiring, I connected most of the wires except for the ones mentioned above I'm just looking to find out the exact location of the BIU or what it looks like so I can easily locate it. Or where to look in the driver kick. Also, would I be able to connect directly to the clutch wire or would I need to use a relay? Thanx

neg or positive clutch? if its postive, connect your start wire to the wire that shows 12v when clutch it pressed. if its a negative, wire up a relay. 85 - constant 12v
86 - ground out when running
87 - ground
30 - to wire that shows ground when clutch pressed.

Back when I installed Ultrastart I saw a lot of units go into service mode and then would not come out of it. Swapping the antenna and antenna cable would fix the problem. Either that, or you are not trying to take it out of service mode using the correct procedure. How are you attempting to do it?
