1998 Honda Civic EX Sedan 5-Speed
Viper 5002 alarm system

DEI 520T Backup Battery:
- RED to Constant 12V w/ 15 amp fuse
- BLACK to ground
- GRAY to RED on Viper w/ 15 amp fuse
- BLUE to ?

1. Distance of inline 15 amp fuse from the constant (+) 12V source?
2. Blue (520T) goes to where and is it fused?
3. GRAY (520T) to RED (Viper)….where does the fuse go?
Thanks in advance for your help.

Don't take this the wrong way and I not trying to sound like a smart azz. BUt did you see the directions that came with the dei 520t? It has a diagram that shows how to wire this up correctly. ANd it has a picture. And its going to be the same info that I going to post.

 

Yes it has instructions, but i am confused as I have read elsewhere different wiring.
BLUE tap into H1/7 (-) Instant Trigger Input?
Also I read:
BLUE to H2/2 (-) hood pin input Zone 6?

Is the BLUE wire fused?
General question regarding fuses...does it matter where in the wire an inline fuse is placed?

 

Np, just checking. When I use the dei 520t I like to put it on its own trigger source. This way the unit is not bypassed by the npc of the dei alarm brain. Example- If a theif leaves a door open when tampering with your car. And that same trigger goes off more then a certaint time. That zone is bypassed for 30-1 hour. Or until that zone closes and re triggers.

I allways tie the 520t to the blue neg input trigger wire on the alarm brain. The will report as a truck icon on the 2 way remote. So if you are going to add the trunk to your setup. Tie the trunk into the doors. Really it a door anyways. So now your trunk will report as a door.

When you tie the 520t into the alarm. Keep the fuse on the alarm. Tag the grey wire before the fuse on the alarm as the diagram shows. There is no fuse on the blue wire.

Use the the hood pin wire for the hood only. If left open the npc will kick in and the alarm will not be triggered by the 520t if the theif unplugs the battery. You do not have to remove. Relocate any fuses.

 

The fuse is always placed as close to power supply as possible.

The blue lead is the 520T trigger lead, it is a low current ground so it does not need a fuse.

The blue lead can be connected to any neg.(-) trigger input on the alarm, [like H1/7 and H2/2] it is best connected to an unused input, if none available it can be paralleled in with something else, along with the hood pin to Blue H2/2 hood pin input Zone 6 is the best, as there is no load on the trigger like the trunk/hatch input or the door input, [both have lights as loads] either one can be used but the load, [light] would have to be diode isolated from the back-up batt. or back-up batt. circuit will be damaged. 94

 

Thank you both for responding...

Tie the 520t to the blue H1/7 (-) input trigger wire on the alarm brain
- ONLY the 520T should be on this H1/7 trigger?

To what trigger should I tie in the BLUE from 507M Tilt sensor?

 

Use the H1/7 for the trunk/hatch trigger.
The 5002 has two extra sensor inputs, [next to valet/program button] use one for the tilt sensor, [507M] and the other for the 520T. 94

 

507M Tilt sensor has no harness to connect to the 5002 ... only 3 wires.

Thanks.

 

pm me, I have a extra harness that will plug in. I can send it to you for n/c. I am going thru my scrape been and tossing all old alarms and everything thats not really needed or is not working.

 

PM sent...Thank you very much for your kindness.

fcm: Thank you for your help also!!

 

Mailed out today!

 

Bless you and thank you very much.

 

I bought the 520T off eBay for $16! Then had a BB installer put it in for $29.99 which I thought was worth it since it looked like a royal headache.

I PM you...have not received the harness yet, hope it wasn't lost!
