2002 silverado, alarm/remote start

Thanks for the info.   

I was looking at the download section and came across an install guide for a 2002 Escalade, supposed to be the same as a C/K truck.   Anyway, it shows a Light Green wire in the middle connector on the BCM that is the driver door only unlock(negative signal).   If this is true, could you just wire the first unlock output (-) to this and used the second unlock output (+) from the DLP-P4 for the all unlock signals?   

I intend to measure all these signals and make sure they are correct when I start the install.   I have the electrical schematics for the 2003-2006 trucks but haven't found one yet for the 2002.   I will attach the link to the 2003 schematic in case anyone could use it.   There are a few other years on this site also.

another thing you need to be aware of is that the DLP-P4 also changes the pink wire to POSITIVE. so you cannot just connect it to that wire at the BCM without changing the polarity back to negative with a relay. no matter how you look at it, your gonna need a relay. unless you just forget the driver door only unlocking altogether.

Yes, I thought about that.   It looks like you might could interrupt the negative unlock output wire between the Remote Start door lock connector and the DLP-P4 and use that.    The other 2 outputs would still be inverted to positive signals by the DLP-P4.      

You seem very familiar with the Omega brand systems.     You are saying use the Pink wire for the driver door unlock.   The AL-2000_EDP drawing shows the Blue  wire as Unlock #1 and the Pink  wire as Unlock #2.     The Omega tech rep I emailed said the first pulse turns on Unlock #1  (Blue) and the second pulse turns on Unlock  #2 (Pink).   Wouldn't the first pulse need to trigger the driver door unlock circuit and the second pulse trigger both doors?    Or am I missing something?

I appreciate your help, I just want to try to figure all this out before starting the install.    Omega's installation guide is only 2 pages, and not very clear on some things.   If you look at the owner's manual along with the install guide, it helps clear up some things.   I'm not an installer, but I have installed a remote start on my 2005 Silverado and I have worked in the electronics field for 34 years.
