Illuminated Entry with Negative Door Pins

Hey there,

On my alarm i have a negative and a positive door pin wire. The way i understand it you use only one wire; the one you need. So i have negative door pins and my alarm also has the feature of illuminated entry which is also a negative output from the alarm.

So therefore this is the way i look at it. I close my car door and arm it; illuminated entry is now activated for 30 seconds or so i beleive but being the car was just armed it checking all the sensors such as door pins now that wire right now is being grounded for my illuminated entry. So one would think that because of this when the alarm verifys that the doors are closed (by checking if there is a ground or not) it going to think they are open and bypass that sensor.

So can someone tell me if i need diodes or anything because this part kinda confuses me, Or are alarms smater then this andi just dont know it..haha...... what can i say its my first alarm install (you gotta learn somewhere). I hope this wasnt to confusing for those who read it.

Thanks, Jeff

Hey there

My car is a 85' mazda 626. Whcih does not have illuminated entry already. I actually was thinking maybe it did not illuminate when you armed for that reason. But my dad has a Grand Prix which has a new Viper alarm....(not sure what model) with command start/keyless entry/alarm and it illuminates after you arm the car for about 30 seconds so this made me think that maybe mine did to and you had to do something special for it....

thanks, jeff
