just got this keyless entry alarm with trunk release...,i have never done an alarm and want to do it myself! Everything i need is inside car under dash right?

 

You need 2 relays for the power locks, i found the wires by removing the dash driver speaker
you also need one more relay for the power trunk wire is in the glove box
what year is your vehicle ?

 

91 mustang 5.0

 

be aware that you will be getting into the critical circuits of the cars ignition and that if/when done incorrectly/poorly will make for an expensive repair. Security is really not for the faint of heart or inexperienced honestly. I did my first alarm after I had been installing for 8 months and if it were not for my manager standing next to me telling me when to stop, I would not have attempted it. Either a cheap, or a badly installed alarm in the worst case scenario will strand you next to it somewhere wondering why it will not start.

The doorlocks are one of the more complex systems. It is a 5-wire reverse polarity which means you will have to be able to diagnose the correct wires(of the 5), the master/slave switch and then insert the relay corectly or you will blow out the door-lock circuit.

 

ttocs is correct i seen many car have problems with alarms and its always the installer
you have to be very careful you have to double check all your connection, and when doing the power locks always use a fuse before the relays just in case

Like the configuration above, the switch, when moved in either direction, applies both power and ground directly to motor legs without the use of any relays. Except, at the switch in this case, both motor legs rest at ground . Therefore it is only necessary to change the polarity of one motor leg to lock or unlock the vehicle.
