g'day if you want to wire up calais pop ups into an sl or an exec you will notice there is no plug for them next to the battery. berlinas, bt1's and calais's have a 3pin plug that comes out where the drivers side head light plugs into the body loom to wire up the relay for the pop ups (provided you have the loom with the relay for it) there are 3 wires; black, orange and white black is constant neg orange is constant positive white is negative trigger i used the low beam (brown wire) as a trigger and converted it to a negative trigger with a relay hope this helps cheers
