I will try to answer...
MO in TO:
Has anyone installed the interior control I have read about that comes in an SE for aiming the headlights? I notice there is a coil attached to the projectors that appears to have the ability to move the assembly left and right, while the height level is manually adjusted from what I can tell and read in other posts using the small white plastic screw on the housings. Is it necessary to install an interior control as well?
Jaak:
I've not pursued it, but I've often wondered, if that's there, what about the rest of the HID wiring?
Jaak, the interior aiming leveler wiring for a murano that has no HID *is not* there. Even the IPDM control modules are different.
So far there are 3 version of IPDM: one for base murano, one for medium loaded murano (with VDC and HID) and one for fully loaded murano (VDC HID NAV). Retrofitting the auto leveler inside the cabin on a base murano will be very challenging as the wiring and the electronic control module must be retrofited as well.
Yet, for "MO-inTO", dont worry! This should not discourage you to retrofit that oem HID headlights. IMHO you dont really need the autoleveler. I have several vehicles before murano that have HID but no leveler feature in the cabin. There is a small plastic screw behidn the headlight to adjust the aiming of the HID beam. I used that one to aim my HID properly after retrofit. So far, no one flash their headlight!
The purpose of the in cabin leveler is not to substitute the small white screws' function. Anyway, only a small vertical angle of the HID cut off beam is changed if you use the in cabin leveler for adjusting headlight.
Example 1:
Let say you go to The Homedepot and get 90lbs of concrete and haul it home, it will lowered your murano right? So you can raise the headlight beam by using the leveler instead of opening the engine bay and use the plastic screw. Then you can raise it back up once you unload all those loads fromk the murano, again using the leveler.
Example 2:
Imagine if you are driving on a hilly roads, at night. Sometimes by raising the headlight further (higher) will provide better plane of view behind that roadbend at the back of that steep downhill.
Instead of you having to stop in the middle of nowhere, adjust the beam using the screw in the engine bay, you use the leveler to raise your beam.
