I want to wire some additional lights to illuminate with the dome light.. does anyone know what color they are in the harness before I have to pull out a tester?

 

I have 2 wires in my xlt.. they are orange/green and black/blue.. but I THINK the dome light is orange/green, double check tho to make sure.

 

nobody knows for sure?

 

According to the CD it's LG/OG and BK/LB
The LG/OG comes directly off the battery saver relay and powers the map lights
The BK/LB goes through the lamp relay, and powers the interior courtesy lamp

 

You want to use the BK/LB. The Orange/Green Wire is constant, always on 12v. The other one is switched with the dome light.

EDIT: I know for sure.

 

BK/LB is black/light blue? Thanks for the help guys.

 

Yes sir...

 

Thank you muchly. I assume I can patch into it in the main bundle running under the dash down towards the transmission tunnel?

 

If you can find that wire there and you are sure that it is the right one, i dont see why not. The only place I have tapped into it was actually at the dome light so I dont know where else that wire can be found.

 

Black with light blue stripe only runs to the dome light, so you should be able to tap into it under the dash. I always throw a meter on the wire just to make sure it goes where I think it should. This circuit should only be powered when the door is open. Be aware that the battery saver relay will shut this circuit down after a while to preserve the battery.

The Light green with orange stripe is a constant feed circuit that also serves the glove box, instrument panel, and ALSO the relay which provides power for the BK/LB circuit. Which means if this circuit blows a fuse, out go the interior lights. This one also uses the battery saver relay, and will drop after a certain time. I'll try to find what the delay is on the battery saver relay, anyone know offhand how that works?
