was wondering if anybody knew what part u have to hack into to make underglows, interior neons and anything of that nature to flash with the exterior lights

i just added a couple of white neons inside that come on when my door pin is open and on a seperate switch for when the door is closed (my dome light R.I.P been gone since week one....2 years later....) and was trying to figure out how to hook them into the alarm

 

So you want the neons to flash when you arm and disarm the alarm? You could tap into the wire that flashes the exterior lights but i think that would result in the neons going on when you put the lights on also.

 

i used to know how to do it when i put some underflows on my friends t-bird but now i dunno
