remote start and dome light

i found the problem with the remote start. haven't tried it yet. but i had the ground in wire for the GMSL just to the cars ground and not the remote start ground output while cranking. hopefully that will solve it. so should i change the wire for my dome light from the remote start. he gray/black wire on connector 1 on the gmsl should go to my dome light supervision wire. black plug on BCM gray/black wire.

for the dome light you can use a relay to change polarity.... connect the gray/black wire to 87, constant 12v to 30, 85 to your (-) dome light supervision from alarm, and constant12v to 86.  Reprogram the bypass after you connected the blue wire to the remote start BLACK / YELLOW wire. 

i have my dome light from alarm going to the wire trigger wire on the GMSL. so i should put that wire to the alarm door trigger and then do what you said above?

OK. ill try that tomorrow
