3 negative pulses from single wire?

Maybe I am confusing people.

 I have a factory keyless entry system. I purchased a remote starter that integrates with a factory keyless entry system. untilizing your factory remotes, and installing the remote starter properly, the starter sees 3 pulses from the door lock wire(pressing the remote lock button 3 times) then starts the remote start sequence. The remote starter did not come with remotes. I need to send it a negative signal 3 times in order for it to work. Since I dont know how to GET a signal from a single wire lock system, thats where my problem is.

i think he's installing an add on starter to the factory keyless.  if this is the case, you are looking for the lock motor wire which directly feeds the actuator.

regardless of how the switch works (multiplex, databus, etc...) the actuator requires +12volts to operate.

if your add on starter only accepts a negative input, use a relay to invert the polarity of the lock motor wire.

press lock 3x on your factory remote - done

i was so amazed that nobody could figure out what this guy needed that i just had to throw an answer out.

p.s. my advice comes free!

 Thanks guys for all your help. In the end I did get the info I needed, along with the exact location and color of the wire. AUEX was the first one with the info I needed, and has graciously asked that the money I was going to send to him be donated to this site instead.

 Thanks again for all your help.... I'm sure it wont be the last :)

Well, thats cuz crimestopper sux when it comes to their tech department....Ive been having some problems with my install as well and they suck!

Anyhow I think this diagram I pulled off another site might help but Id dbl check with one of the pro's here first......gdluck!
