Hi, I recently pruchased an Phoenix Digital PD-175 alarm sys. and I recieved it and would like to install it myself. I check around to see how much an professional install will cost me and the lowest I found it was $300 so needless to say --here I am. What I basically need is all the information you guys feel is neccessary since I have limited experience installing alarms in particular (I have a lot of experience with other electronics, stereos and computer but not alarms). If somebody has an wiring diagram for my car that would also be very helpfull.
Now the important info:
Car: 2002 Dodge Neon Base Model
- Manual Transmission
- No Power windows or locks (I plan on installing power doors in a couple of days)
- No Key Chip
Alarm: Phoenix Digital PD-175
Here is the image of the wiring diagram for the alarm:

Well there will be one wire that no diagram I have seen has. So go find the oil pressure sender wire before asking for the rest of the diagram. If you can't find it then get a different alarm.

Always check info with a digital multimeter.
I promise to be good.
Tell Darwin I sent you.
I've been sick lately, sorry I won't be on much.
I think that RED wire is for the alternator sense wire, auex.

Yeah Jeff is right, that red wire needs to be hooked up to 12v+ constant to monitor the voltage. I had a guy who tried to install one of these and it didn't work so I helped him find the oil sensor wire and that didn't even work, so I decided to try hooking up to 12v+ constant and then it worked.
I don't think that unit is designed for manual transmission vehicles though. Don't install the remote starter features if it is not. You can buy a peripheral Neutral safety switch if you are so determined to install the starter feature. I don't have the link to where you can buy one, but they are out there.

I think that I won't be installing the Remote Starter feature. It just seems to much trobuble and I can't image that I will find it that usefull anyway.
In any case it does seem that this sys. was designed for automatic trans. but I do have a couple more questions.
The RED wire from the 7 pin connector as it says needs to be hooked up to the 12V+ which is energized after the eninge has been started. But the oil lamp goes off when the engine starts therefore de-enegizing the 12V+ hhhmm. It does seem that connecting it to the alternator wire makes a lot more sense.
Also it says that the ORANGE from the 7 pin connector goes to the BRAKE PEDAL LIGHT??? I would assume that it was meant for cars equipt. with automatic trans where you need to depress the brake pedal to start the car. Now since I have no such thing, would it be possible to hook it up to one of the constant 12V+ power inputs or even to a switch or one of the lamps that goes on when put the key in the ingition.
Suggestions are greatly appreaciated.
There is a switch above the brake pedal that triggers your brake lights when you press on the brake to let drivers behind you know that you are braking. One of the wires reads 12v+ when the brake is depressed and that is the wire you need to grab.
The red wire needs 12v+ constant (found in the ignition harness where you also will connect the fused red wire in the 12pin harness) so the unit can monitor the voltage and look for an increase when the alternator kicks on.
