Installing alarm on my 07 mustang

Thats up to you.

If you have never installed an alarm or remote start before, I would recommend that you take it to a pro. You could accidently do something bad to your car and your warranty wont cover it.

If you insist on doing it yourself I can send you the info that I have on that car. You will need to PM me your E-Mail address.

 

2007 Mustang GT wiring

 

Important info thats missing, read the notes about the pull up resistor, its absolutely necessary

 

When I did the install one my car (there is no time problems as with a customers car), I installed the hood pin switch, siren, LED and anything else that needed to be done. In my case, I used the tach signal (not necessary with most systems today) so I located that wire ahead of time.

As far as which wire to use, all wires should be checked before attaching to it. Any good installer will know that.

Also notice in my notes that the constant 12-volt wire is only a 20-amp supply. DONT use it for the remote start. Run a fused wire to the Battery.

 

Your question is confusing me, the trunk release should be white/purple and negative trigger. I always use a relay for truck release unless your module has built in relays for trunk release.

For the trunk trigger use the white/yellow. Your alarm module should have both negative trigger and positive trigger inputs, use the positive trigger.

You the negative trigger for the door pins. To prevent false triggering remember to use a pull up resistor or diode isolation. (in your case pull up resistor is easier)

Hope I understood your questions

 

Neg pulse means that the wire has a voltage on it when whatever device its hooked to is off. But when its on it does to ground.

Diode isolation means that we can use 2 or more (this is an example) pin switches on a single trigger line, or two triggers on a single pin switch. My car uses a single pin switch for both the hood alarm trigger and for the remote start safety. Diode isolation makes the alarm think its hooked to two sepeate switches.

Get help from your installer freind. If your alarm cannot handle the current to open the trunk it will do damage to the alarm module (better safe than sorry)

The Ford GEM tests itself about every 20 minutes. When it does, the alarm will go off. The pull up resister prevents the alarm from going off every 20 minutes. One side will hook up to a constant 12-volt source, the other side will go to the Green/yellow wire at the SJB (the resistor needs to be 10K)

We can also prevent false triggerring using a diode in line on the green/ yellow but the resistor will work

That person is obviously not an installer. Bad arguement. They can still pop the hood and cut that battery wire. First the hood needs a pin switch on it, so that when it opened the alarm goes off. Second, most cars the hood is opened from the inside. Third it takes just as much time to cut the battery wire as it does to locate and remove the alarm fuse. Also no one knows the fuse is there unless you put a big neon sign saying its there.

The constant positive wire in the car is only rated at 20 amps. NOT a good idea for powering a remote start

Those are more than likely the ignition kill wires, if your car has a transponder in the key, then ignition kill is not necessary and a waste of time.

Factory Disarm should be hooked up, the rest are optional.

And I still feel the same way. I always encourage people to do things thenselves and learn. And I respect your decision to do this yourself. But for a project like this you really need the help of an experienced installer.

Post back let us know how its going

 

Pin 30 goes to ground, pin 87 goes to white/violet. Pin 86 goes to a constant 12 volt source and finally pin 85 goes to red/white

To change polarity, Pin 87 goes to the blue wire. Pins 86 and 30 go to ground. Finally pin 85 goes to white yellow.

 

You can just attach the remote start wire to the car starter wire, you don't need to cut the car starter wire.

I dont like wires hooked up all over the place, it makes for a sloppy install. In my car all the power wires go to the same place, the fuse is a 40-amp.

Make sure I got this, one side of the resistor goes to a constant 12-volt source, the other side to the door pin trigger wire. If thats what you meant, you've got it.

 

I like dome light supervision. You dont need it but its nice to have.

Pin 85 goes to the alarm Black White. Pin 86 goes to a constant +12 volt. Pin 30 goes to ground and pin 87 goes to your door pin switch wire.

Every alarm is different so I have no idea what your LED is telling you. Check with the owners manual or a dealer for that perticular brand.
