Hi Steven,  I have full Japanese wiring diagrams for 2002 - 2008 ANH1# and MNH1# and I have translated much of it to English.  I have mainly concentrated on the A/C and engine and  I havent yet translated the body and lighting but I could do those sections for you if it can be narrowed down a bit.   (The full set is about 400 pages long!!)

 

Ive attached the index to the wiring schematic pages.  Can you identify those you need?   I would also need to know the frame code and year

Cheers David

So Sunesh means the light stalk.

 

In Auto, if the engine is stopped the lights turn off.

If the ignition is off the lights will not work on automatic.

 

Check you do not have the sensor in the middle of the dash covered.

Do not clean the sensor with glass cleaner.

 

Do all the other functions on that light work correctly ?

Yes, i has try it ones enjine running infact tested on night while running

All function light all ok

I just clean the sensor with wet and dry cloth.

Headlight sir.

Do you mean the light by the shifter, or perhaps the one in the dash panel ?

The headlight sir, the light shall ON ones get dark.

I had change the switch on steering but nothing happens, therefor looking for wiring manual to see any relay for this unit or not.

Good morning Sunesh - I am afraid I am not sure what you mean by 'auto light' is this an internal or external light?

What makes it automatic?

The only item I can think of is when it gets dark the headlights will come on, is that what you mean? 

Yes, i mean the headlight. The light will automatically ON ones get dark.

Hi, Any one know or have wiring diagram for auto light.
