I had a dealer put in a viper remote start and alarm. They hooked parking light flash, but i had to take it back to the dome light supervision put in. no charge of course. I thought that would include illuminated entry though, meaning my headlights and puddle lights would work also. My factory did all that. My question is what wires and relays do i need to do this. Any help would be appreciated. It's a 2008 ford f-250 lariat psd

I don't have any wire color or wire location for you, but I can tell you that you need to be very careful when connecting to the wiring in the truck. I am pretty sure that the wire(s) you need are located at the light switch, but they are negative wires. I have had to repair several of the switches for several different shops in town. They all say they did not check the polarity and assumed it was positive.
