Can anyone help me with the dome wire? I have two harnesses on the right side fuse box but can't determine the correct wire...
Also for anyone doing this install,save yourself the hassle and just go into the driver door t fetch the factory arm/disarm wire for your lock and unlock.

it looks like the top harness in this pic is the 20 pin... but it doesn't look like normal gauge wire going into it. and its hard to probe with it plugged in because of the clip on the top... any ideas?

turn the dome lights off in the car via the switch on the lights it self. Then use a test light to find the dome light wire, the light should illuminate when you find the correct dome light trigger

thanks i got it.. it was that harness... right row of pins 3rd from the top... i got confused since it looked like ribbon wires...
two more questions...
1.) i used the factory arm/disarm switch as the lock/unlock wire... i don't have to also wire the factory arm/disarm wire as well right???
2.) i'm considering using Aux 1 & 2 for window up/down and the wire scheme says to use the factory arm/disarm wire... again since i have the door locks using those wires, if i want to tie in the aux outputs, should i diode isolate each of the triggers???

No, you dont need to use the factory arm/disarm wires on the remote start, just the blue and green door lock wires. But make sure you change the unlock output to double pulse in the remote start programming settings otherwise it might not disarm the factory alarm. And for the windowsup and down i normally just tie the aux 1 and aux 2 wires into the appropriate blue and green lock wires so you dont have to run as many wires into the door
