Strobe and 2nd siren install

Hey there, i'm the latest newbie here!! I recently had a Prestige 996a alarm/remote start installed. I had a mine piezo siren installed in the cab and i purchased another one from ebay but the place I had the alarm installed wouldn't install it since I didn't purchase it from them. I don't want to mess anything up but since I have the extra siren I want to install it. I'm don't know very much when it comes to electrical stuff, but i'm pretty mechanically inclined so with a little help I think I can get it installed. So what do I need to know about hooking it up??

I also want to install strobes inside the cab and possibly outside and need help with that too (I have a separate thread for that though)

Thanks in advance for any help!!!

I recently had a Prestige 996a alarm/remote start installed on my truck. I want to hook up strobe lights inside and out for some added security and confusion for a would be thief. I did a search but didn't really understand a whole lot of what was being said. I'm not very good with electronic lingo (relays & stuff) and wiring. I am pretty mechanically inclined so with a little help I think I can figure it out. I was planning on just splicing right into the mini piezo siren that is in the cab but someone on a different forum (the person who directed me to this forum) advised that I shouldn't do that. A wiring diagram would be really helpful!! Thanks in advance!

I also want to install a 2nd mini piezo siren in the cab. I have a separate thread for that though.

Thanks again!!

the Installater, I was told hooking it up that way will put alot of stress on the alarm brain and you have to hook something up in between it..

bobk, sorry about the 2 threads. I wanted to keep them separate because from past experience in other forums if you as more than 1 question in a thread it the topic always veers off and only 1 question you asked gets covered and everyone forgets about the other question(s).

I personally have 2 mini piezo sirens and the siren that came with the alarm hooked up to the siren output and it works just fine.  If you want to add strobes you will need to wire up a relay to the siren output in addition to the sirens.

As a side note, I put the mini piezo sirens in the air vents on the sides of the dash.  Sat in the car and set off the alarm.  All I can say is if a theif wants to sit next to one of them long enough to rip out my stereo, he's not gonna have enough hearing left to enjoy it! 

Now for the strobe install.....I still have no idea how to hook it up.

Anyone have a diagram?????

Yes I have 3 sirens connected to the same output, if it were me I would go ahead and tap into the existing piezo that you have.  As for the strobes, I think you need to use a seperate relay so you don't overload the alarm brain.  Try this diagram I lifted from elsewhere on this site.

Using a 30 amp SPDT relay, connect terminal #87 to constant 12 volts positive WITH A FUSE.  Connect terminal #85 to ground, terminal #86 to the positive wire going to the siren, and terminal #30 to the positive wires on the strobes.  The negative wires on the strobes go to ground as usual.

Maybe one of the pro's around here will give their input on whether I got this right or not.  I installed my first alarm 2 weeks ago in my car and had never messed around with relays before.  Everything I have learned has come from this site.  Search and dig around...most of the answers are here.
