I just got started on my car alarm install. I am running all the wires to where they need to go today, but make all the connections later. I am taking my time to have a clean install on this thing. The only thing I am confused about is the Parking Lights and the Interior Lights polarity. I have checked the Wiring Information on the site for my 86 Mustang, but I am unasure how to find thepolarity for these wires.I have a Volt-Meter, but I am not sure how to check the +/- with it! Any help would be great!

Thanks

If you want to learn first hand how to verify each connection point. Please do the following.


DOOR TRIGGER: Set your DMM on DCV / DC 20 volts range. Connect your (-) negative DMM lead to the chassis frame / ground. Probe the trigger wire which you believe is the door pin. If it is, then it will show +12 VDC when you depress the switch, and goes back to 0 volts, upon the rest / open position.


PARKING LIGHTS: Set your DMM to DCV / DC 20 volts range. Connect the (-) negative DMM lead to chassis frame / ground. Probe the wire in the light switch which you suspect as being the one. Turn on the parking light switch and it should show 12 volts, when you turn it off, it will go back to 0 volts.

Remember, if you probe the wrong wire, such as the dimmer light switch, it will vary the voltage with the setting. So make sure it is the actual switch, as it will not vary at all, or very little.

Lesson 101 is over . . .

Between the post I have figured out that the wires are positive. Thank you for the information!

Teken, I do want to learn and I am trying to understand your post. When the door is closed, if I am reading it correctly, I will get a 0 volt reading and a 12 volt when the door is open. This means it is a positive switch, correct? If it was the other way it would be a negative switch? I am assuming that a (+) or (-) switch is something like a relay. If it is a negitive, then it would be using the Normally closed position to send power to a circuit. Am I correct in this assumption?

Only trying to learn and understand things so that I can do better work in both now and in the future!

Thanks!

Just wanted to give you a few reference materials to speed along the install process.

I am glad you want to take time to learn and understand how to check each connection.

Many others simply want to read the charts, and move on. That does nothing for the person who wants to learn, or fully understand what to do when a problem arrises.

If you have more questions, just ask. There are many knowledgable members on this forum more then willing to take the time to explain to you any question you may have.

Here are some resources for you to review. This one is about diodes, and how to use them for common applications.

This is how to use your DMM to test your circuits as I explained earlier.

Practice on your vehicle and on others, to see, and to fully understand the process.

Everyone learns by doing. Practice these simple procedures when and where you can, and future installation(s) will become more comfortable.
