So I got some mirrors from AU that have the puddle lamp at the bottom of them. My plan is to wire them up to the interior dome circuit that comes on when you unlock the door so they will act as approach lighting after I unlock the vehicle.

This will be a description of all the wiring in the mirror as I ran a wire through the door connector when I did my headliner change to black so I already had the wire I need at the mirror connector in the door. If you remember I picked up that wire in the headliner harness that goes up the driver A pillar. This was the easiest place to capture this circuit as it comes off the BCM and goes deep into the dash before coming out at the A pillar. So these lights will come on any time I turn on the interior dome lights. There is a circuit in the BCM called "puddle Lights" that I would guess would not be so closely tied to the dome lights. I am sure they would still come on when approaching and unlocking, but maybe not when you turn on the interior dome light manually with the doors closed. Not sure how that would work.

The plan is just to use the AU mirrors outer case, lighting circuit and just transfer everything else over from the US version (mirror motor and heated glass)

Mirror Removal:
Removing the mirrors involves removing the door panel first. You then have access to the trim piece that has a access door in it. Un-clip the access door at the bottom and the top slides out from the surrounding trim molding. Some pics:

Using a #25 Torx unscrew the two screws you can see after you remove the trim door:

Leave the top one screwed in a bit to support the mirror in case it falls out when you do the next screw.

Then unclip the doors weatherstripping to revel the third screw holding in the mirror:

Then the mirror should pull off. You may get some resistance. Lift it up and out as there is some rubber adhesive holding some of it in.

Removing Mirror Cap -

Removing Mirror Glass - Now that the cap is removed and the back is exposed you can get your finger through the case in two spots and push on the back of the mirror glass. When you do this 1 of two things will happen. You will pop the glass off the motor. Or you will pop the glass and motor out of the mirror case. IF the glass comes off the motor that's fine, it will snap back on once you put it all back together. You would then have to remove the motor. It is just held on by 3 friction clips. You can see them from the front of the motor as there is access holes to get to them, but the holes wont help you remove it. But they do help in seeing where to pry on the back at those three spots to remove the motor assembly. We are really only removing the motor because we cannot get the motor connectors through the case without moving the motor out of the way.


Harness Removal - So what I did was remove the 2 wire lighting circuit from the AU mirror so I can add it to the US version that had the heater circuit already in there so I can retain my heated glass and just add the lighting. To do this I removed the harnesses from both mirrors to add the wire and splice into the existing ground inside the mirror. Thinking back I think I could have done all this work without taking the harnesses out of the US mirror and just fishing one wire of the lighting circuit through the wiring chase to the connector but then I would not have been able to tape it all up into one harness.

So both of the motor connectors together are pretty fat so they won't go through the wire chase at the same time taking up the same space. So tie a string on to one and send it through the wire chase first. The harness can move back and forth in the wire chase so I tied the other end of the string to the far end of the harness so it would pop out first and I could pull the one connector through before the other one. Leave the string on there it will help you get them back through.


Oh one other thing that won't go through the wire chase is the big bulb holder so at the sides of the bulb holder you will see a little window with some silver in there. That is the terminal release. Get a pick and push on the silver piece while pulling the wire from the back of the bulb holder. Slides right out. Here is one removed next to the window where the other one is still in there:


Harness Modification - So when the lighting circuit comes out of the AU mirror it is made up of a bulb holder with 2 black wires with a terminal on each end. We only have room for 1 more circuit on the mirror plug so that will be 12 volts for the light and the ground (the other black wire) will have to splice in with the existing ground in the mirror and that ground is for the heater circuit. First step is determining which of the heater wires is the ground. Not an easy task because they made both of those wires black as well! So take the harness back into the car, plug it in on the door, start the car and turn on the rear window defroster. What we are going to do is determine which is the positive and that will mean the other wire will be the ground. Using a test light see which one of the connectors that goes on the mirror is energized with 12 volts positive. Then switch off the rear defrost and confirm the 12 volts went away. Then mark the other black connector as the ground (you will see I did it with a red pen). That is the wire we are going to splice into.

Remove all the tape from both ends of the harness tubing. I put the spice right before the heater wires exit the tubing. So I cut a slit of about 1 inch inf the end of the tuning that is at the opposite end of the connector, folded it down on it's self and slid the tubing as close as I could to the main connector to give me room to do the splice. Take one of your black lighting circuit leads with the terminal on it (either ones fine they are both black) and insert that into the open cavity on the main connector. Line up the two bulb terminals so you can get a jist of how the wires will run together along the harness (want them the same length). Then cut the loose wiring circuit wire and the harness ground wire in the same spot to give you your splice location:


Strip wires, put some shrink tubing on the wires where you can, and crimp the 3 ground wires together using a bare crimp connector:

Move the shrink tubing over the bare crimp connector and heat the shrink tubing, Move the harness cover back over the splice, tape up the harness from connector to splice securing the one loose light wire with the harness. Finished Product:

The connectors and terminals for the mirror are the JST HL series:

JSt Part Number SSF-21T-P1.4 is the female terminal and goes on the car side connector. The male (mirror) side I already had on the end of the wires I took off the AU mirror so I did not need to buy any of those. But if you are doing some custom wiring get the male pins with JST part number SSM-21T-P1.4

Not sure if these are the same connectors for the G8, SS, VE, VF, WN but I imagine they use the same ones.
EDIT - Eat my words on that. For the VF and WN (SS and 14+ caprice) they switched to a 12 cavity plug to account for all the extra stuff added to the mirrors. Blind spot warning as an example. So I will change the title of this to 11-13 only.

Since I have the mirror cases completely disassembled I gave them a good cleaning and am putting a layer of black bumper paint on them followed by some clear coat as they were a bit faded from the AU sun. Want to look into LED bulbs for them to match the white color of the puddle lights I have at the bottom of the door.

Will try to do a video of them in action once it's all back together.
