Need help bypassing factory alarm when using remote start and trunk pop feature.   Most info say connect to lt GREEN/ red wire in driver side harness but when I do that the factory alarm still goes off and prevent starting, when I put the key in the door and unlock which bypasses the factory alarm it starts but If i hit the disarm button it kill the car and some funky stuff happen.  

I also read to tie into the key sense wire with a positive trigger which didn't really work either but is not a good idea with this car because the key sense wire also makes the steering wheel comes down in this car which is fine when remote starting but every time I hit the unlock button the triggers the steering wheel to move. 

Thanks,

Any help is appreciated,  Q
