how many wires are coming from the harness of the auto dim compass mirror an can you just plug the compass auto dim mirror with the two wire harness an it works or do you have to install a new harness with more wires

 

All you have to do is unplug the harness of your current auto dim mirror, remove the mirror, install the new auto dim mirror with compass, plug the harness back in. You are done!
In case your new mirror also have temp, then you need to wire the sensor wire (this is the hard part). Since I have out side temp display already, I keep the sensor wire inside my car so the mirror will display inside temp.
I installed my Auto-Dimming Rear View Mirror w/Compass and Temp last week. I had no problem to do that at all. If you have any question feel free to ask me

 

thanks that helps alot

 

those were stock in 03?

 

Yes! But it does not have temp, only compass!

 

i installed mine today. i did not have the auto dim to begin with. it works, but when i press the compass button it displays a C. if i press it again it gives numbers. if i keep pressing it the numbers go from 1 to 15. any idea what all that means?? it does not display north south etc...

 

yua i was wondering how easy it would be to add that mirror in my 00 max??

 

it was very easy. i got it to calibrate and it works fine now. still don't know what the 3rd (green) wire is for...

 

How do you get it to read temp? I installed a compass mirror last week and saw that it had an LCD capable of displaying temp, but it doesn't.

 

The temp. display of the mirror needs a temp. sensor probe in order to give a readout. Either you can buy a probe and wire it directly to the mirror, or if you have auto A/C in your car, you can tap into the ambient wire which already has the probe mounted outside the car near the grille.

 

the one i installed has 3 wires. black for ground, chocolate for power, and i am thinking the green one is for temperature. I do have the auto climate. I can run that 3rd green wire to the front sensor to make the temp work??
