I am trying to install an omega rs-120dp add on remote start to a 2003 lincoln aviator. I was planning to use the unlock pulse from the factory keyless entry to trigger the remote start by programming the omega unit to start on 3 negative pulses.
The problem I ran into is that in the driver kick panel, the factory unlock wire is reading (-), then on the first unlock button press, It sees (+) for approx 15 seconds which I assume is for the mirror lights that illuminate the step area. There is no change in polarity, or pulses to be seen even when the unlock button is pressed a second(or third ect) time to unlock the passenger doors.
I am hoping that there is a keyless receiver module that sees each button press and has a pulse which is negative or positive that I can use to trigger the remote start, and that someone can help me to find it, or if there is another way to get 3 negative pulses from the factory keyless remote.
It is for my employers wife, and we dont want to have to go with an additional key fob, which is why we chose the add on.
Thank you for any help.

Can the remote start trigger on a (+) signal? The most common method is to use the lock motor wire.
Here is the info from Bulldog Security : LOCK MOTOR WIRE PINK/BLACK (+) IN DRIVERS DOOR HARNESS
If not, you could use a relay to convert the (+) Lock Motor to a (-) for the remote start trigger input. ------------- Soldering is fun!

Your going to have to use the drivers motor lock leg, which is pink/black. You won't find it in the DKP, you need to go into the door for this wire. It is a positive pulse, so either your unit needs to trigger positive or you will need to add a relay to make it do so.

It wont trigger on (+) pulse but like you said, I could reverse polarity with a relay and that would work if the door lock motor wire sees each individual pulse from the factory remote. She has to push once for driver unlock, and a second time for the rest of the doors to unlock, so I want it to be 3 presses to remote start. The vehicle is 2 hours away right now, so I cant run and check, but if that lock motor wire does see all the pulses, I could use it. Thanks.

OK, thank you very much. That can be easily done. I appreciate the quick responses.
