Help: Acura Integra

Hi,

I am installing (or trying to) a basic alarm on my 1991 Integra: an Audiovox Prestige APS-25-CL. I need some help in the wiring (although I am not completely electroncially impaired):

1) Door trigger. The alarm allows for either a negative ground output door trigger or a postive output door trigger. Would I be correct in wiring my Integra's GREEN/ red (-) wire to the alarm's brown wire? Or perhaps I use the alarm's purple wire?

2) The wiring diagram for my car on this site talks about a yellow accessory wire at the ignition switch harness. Is this wire hot when the key is on/accessory/crank and dead when the key is off? Or am I way off base here?

3) The wiring diagram for my car on this site talks about a BLACK / YELLOW "Ignition" wire and a BLACK/ white "Ignition 2" wire. What is the difference between Ignition 1 and Ignition 2? And which one would I use for the purposes of my alarm? The alarm simply says to connect wire 87A from the relay to the ignition switch.

Thanks in advance for your help. I am desparate here. Perhaps these questions are due to inexperience, but I figure that I have to learn sometime and somehow -- may as well be now!

1. Use the BROWN wire if this is a ( - ) input wire

2. There is power in the ACCESSORY & Ignition ON positions and 0 voltage in the START position

3. Use the primary ignition which is the BLACK / YELLOW wire for the relay hook up

You have now been learned !!

Hi Jeff,

First, thanks for your help. If you don't mind, I have developed some new (certainly related) questions and encountered additional obstacles:

1. I will use the brown (-) input wire for the door trigger and disregard the purple wire. My car is a hatchback model, therefore, I have 3 trigger spots: driver's door (affects dome lamp), passenger's door (affects dome lamp), and hatch door (affects luggage lamp). I would like for all three points to, when opened, set off the door trigger option of the alarm. How should I wire the brown (-) wire to do this? The wiring diagram for my car on this site talks about a GREEN/ red (-) door trigger (is this wire for both doors?) and a GREEN/ black (e) trunk pin. Further, would I have to use diodes?

2. The red (85) wire of my alarm's relay hookup requires a connection to "+12 VDC ignition/crank." Would the yellow accessory wire in my car's ignition switch harness do the trick? If not, which wire would suffice?

3. The large wiring harness of my alarm has a yellow wire that is also to be connected also to a "+12 VDC ignition/crank" wire. Could this wire and the red wire in the previous be spliced in together with the car's yellow accessory wire?

4. And, finally, a question regarding the LED. The LED included with this alarm flashes different codes for different levels of car violation, etc. However, I have a Varad LED strip that has 7 LED's which run in a line. I would like to use this Varad LED strip with my alarm, but am concerned that the wiring for the alarm's LED is not what I need/want for the Varad strip. My strip has it's own circuitry which controls the flashing pattern, etc. What should I do? Simply splice the Varad unit into the line where the alarm's own LED was or use both somehow? (I am not against the two lights on my dash, because I see the utility in knowing that status of the alarm or which points of the car may have been violated.) If I used both, how would I wire the Varad so that it only comes on when the alarm is engaged? (At present, the strip comes on whenever my key is in the off position -- it's purpose is to imitate an alarm.)

Thanks so much for your help. I truly look forward to your reply (as I'm anxious to install this machine ... although I want to do it right the first time, and not mess anything up.)

1. Does the unit that you have not include a separate hood/trunk input ? I would use this as opposed to tying it into the whole system. If you are using the two separate wires as activation wires for the two doors, you shouls diode isolate with a 4001N diode.

2. Use the BLACK / YELLOW wire for ignition source if this is what the instructions ask for

3. I'm not sure I understand the wire that you are talking about because you can't have two different wires with different characteristics doing the same job. Please email me a picture of the wiring diagram so I can help you out better.

4. The alarm's LED out put voltage is probably only about 2 Volts and the varad requires a 12 volt switched connection ( follow the instructions ). You can hide the programming LED somewhere ( ash tray or coin slot ) and have the Varad somewhere visible. You won't have to hook up any wires that connect to the alarm's LED.
