HEllo all its been awhile since I have done car security as I do Custom home audio now. I am adding a remote start with keyless entry to my sister inlaws GMC suburban and not sure on the doorlock wiring.

I have found in some sites to use + pulse to lock and unlock but remember reversing polarity on some gm's as well as - pulse.

Not sure where to go on this one

Thanks for any help

Thanks for the help guys, I got it all up and running this afternoon. the light flash out from the starter was a negative, so I used a relay to convert to posituve and now it doesnt work. It did have a negative out when active so I used that to power the parking lights
