keyless enrty with remote starter
 

Just installed a remote starter on truck. Has a keyless entry feature which truck already has. Would like to not carry two remotes around plus for some reason when truck is running on remote the keyless entry doesn't work. Remote starter sends a negative pulse to lock or unlock and I thought the truck was a negative pulse system. Hooked up wires I found in wiring diagram and lock works but unlock does not work. I used the pink/yellow and pink/ lt green wire in grey plug by steering column. Any one has any ideas on how this stuff works would be awesome. Thank you in advance.
