I have a 1998 Honda Civic EX Sedan 5-Speed
Installing a Viper 5002 alarm system

Add-ons:
Tilt sensor 507M
Glass break sensor 506T
Backup battery 520T
2 Piezo sirens

Please correct me if I'm wrong, but, I only need to use "diodes" anytime more then one sensor is plugged into the same input?!

Since the alarm has 2 Sensor inputs, and I am only using 2 add-on sensors (tilt 507M & glass break 506T) and plugging each one into its own sensor; i need not use diodes?

 

Usually diodes are used when using multiple sensors on the same input. The diode is used to prevent voltage from back feeding into the other sensor. But since you are using seprate inputs you shouldn't need diodes.

 

Great and simple explanation...thanks so much!!

 

u probably use a diode for the 520t blue trigger wire

 

Place it inline between the backup battery module and the Viper control unit? Placing the Cathode towards the Viper control unit?

Should I tap the blue trigger wire into the trunk trigger wire via a diode?

Thanks.

 

yes u can use the trunk trigger but i think ull have to isolate that also
oh and cathode away from the alarm not towards it
heres some images i used to help me when i did mines
