2001 LS Trunk Release Issues

I've been trying to install a remote starter into my 2001 LS and am having some issues with the trunk release. Since I purchased the car used about 6 months ago the release button in the cab hasn't worked, but the remotes always work so I know it isn't a solenoid. So now I am trying to hookup the aftermarket remotes and I can't get them to work. All wiring diagrams I have come across say that it requires a negative pulse to a white wire either behind the switch or in the REM in the trunk. There isn't a white wire on the switch, only a black/white and black/green, but I can't get either of them to do anything, and I can't even locate the white wire in the REM. Any suggestions, with getting the switch to work or the aftermarket remotes?

I've seen this all the time so if this is basic knowledge to you I apologize in advance. There is a button in the glove box that gets pressed by accident and is very hard to see unless you are looking for it. It's a way to lock your trunk if it's parked by an attendant.
