All I want to do is add a LED scanner to my dash.
One from this site. The red lights with the
black on the 2 edges. Check it out.
http://www.blackwidowsecurity.com/catalog/leds.htm
I want to piggy back off the security LED already installed from Nissan.(reason for that is that I want the light to go on only when I arm my alarm) I pulled out the clock/security LED section on the top of the dash and saw only one plug which had a bunch of wires. I am assuming the LED scanner only comes with a positive and negative lead, so which wires will I need to piggy back off of on the existing plug? (which colors out of all the wires on the one plug). The 1 red LED that's in now is blinking so if I piggy back off that will my scanners rhythm be off because of the blinking (is it a constant flow of power going to the LED and something in the LED makes it blink?) What I'm getting at is I don't want the new LED scanner to blink, I only want it to scan back and forth along with the blinking of the original security lamp.
Thanks.
(Thanks to all people who help me rewire my markers.... Mingo, you were a real help)
I'm hoping to do this on Friday, November 10, so hopefully someone can get back to me soon.

I'm assuming that your 'scanner' is a self-contained circuit with some sort of LED array, so you really want a constant power supply vs. power to the Maxima's LED, which is strobed.
If your scanner is simply a bunch of LEDs, then you'll need a simple scanning circuit - you can find one at http://www.allelectronics.com/
By the way, I think they have some 12V LEDs there!
If you really want your scanner to be on only when the Max's LED is blinking, then you'll need a schematic to determine where to tap off for constant power. You could also achieve this by using a voltmeter and probing around the circuitry on the alarm module.
If you wanted to switch the scanner yourself, tap a wire off of the cigarette lighter, which is a constant 12V supply. Your scanner circuit may want a lower voltage (+5V), so you may need to drop the battery voltage with a 5V regulator, or a power resistor.
A bit of work, but not too bad. Good luck
