Without it the sensor will fall out.

There is the possibility that the wire's too short to reach - I'd be surprised, but that might be why they didn't hook it up.

As for the headlight height sensor, I think the rear sensor is on the driver's side as well (I had my rear wheels off today but forgot to look).
Crap, you are good. I think I found that clip on my old brakes. Is it this guy below? Wire looks plenty long, maybe I'll try it next time when my wheel is back off.



I took off the driver side wheel today and I think I found the box you were talking about. When the car was originally lowered, it had no problems. But I had to have the shop take the rear spring back out to put in the perches for the KW. That's when the headlights started aiming way high. I adjusted them back down.

Is this the box in question below? If so, what kind of damage is normally done? I didn't see any breaks in the wire and I don't know how to test the box. What other consequences does having this box not functioning have?



The driver side has clips for a brake pad sensor but the wire is not to be found anywhere. So I assume this sensor is passenger side only.

Thanks for your help, you really have good expertise in this.
