strobes w/ alarm

This is my second post (I think). I have a 94 Mustang with an audiovox pro 9842b alarm (professionally installed). I have wired my neon underbody kit to my parking lights successfully with no relay (once I get more time I will install one) and now I have purchased a headlight strobe kit from Optx. My goal was to wire them up so they only strobe when my alarm is triggered (separate from parking lites—don’t wanna get pulled over b/c of flashing strobes). If I could afford to, I would purchase the Whelen Police Strobes like this: http://www.spdkilz.com/z06dusk.html (I am not that rich…so I decided to go a little bit cheaper!) Now to my problem: I thought I could tap into the siren using a relay so when the siren goes off it would trigger the relay to turn on the strobes. I was successful but the problem now is that my siren only “chirps” sometimes. Once I removed everything the siren works properly. I had the relay and strobes grounded to the neg terminal of my battery (since everything was close to the it). This is the setup of my relay: 87->12v constant w/ inline fuse 86->wire tapped from siren 85->ground 30->pos wire from strobes Am I doing something wrong? Or is there another way to do this? I've seen the strobes @ nite and it looks great…but now I want to put them to use. And I think my neighbors are going to kill me if my alarm goes off 1 more time…I would love to try to finish this project! thanx in advance patrichmhs02

how would i go about doing that

your 12 volt output from the alarm to 86 on both relays 85 of both to ground 30 of both to fused 12 volts 87-of one relay to the strobe pack and 87 of the other one to the siren.Good Luck

thanx for the help, though i am a little confused on where to find a 12 volt output from my alarm? also, would i have to add another relay if i wanted to wire another set of strobes to my tail lights? thanks once again

your siren out put should be 12 volts....add a relay for item that you will run off the siren wire....just dont go over boardGood Luck
