they were still standard in 04

 

You are right.

So 05 is when they became apart of the SSL package

 

man I keep searching, havnt found anything solid

 

Sorry to bring this thread back from the dead but it is possible to wire up the OEM leveler switch. I haven't done it myself yet but will be in the future when I get my hands on the leveler switch.

There are 3 wires on the leveler's motor (blue, green and orange). One is for ground, another is (+) when the headlights are on, and the last wire is a voltage comparator signal. I haven't had the chance to verify which is which with my Power Probe yet, perhaps someone else can chime in here with this info? Basically when the headlights are on the motor powers on, reads the voltage from the third wire and adjusts accordingly. The adjuster switch is a potentiometer which varies the voltage output through a resistor. You will also have to run 2 wires from each light assembly into the cabin to the switch (the 2 wires other then the ground).

In the future I should have a more definite write up/how to guide on this subject. This is all the information I have for now..

 

is this actually possible? i'm thinking you need to get the leveler roller and then connect it to the etacs ecu. but do all model years have what's necessary?
