PS, the later model SXE10 JDM mirrors I believe are the same as the USDM ones.
I have one and the cover is not held on with 3 screws.
The housing part has 7278 written on it

Hate to dig up old stuff. Can someone help me with wiring on an 2001. I have the pigtail from the JDM switch. I want to make a plug and play harness. I have a Toyota radio harness that plugs into the Us harness. Basically The JDM wires are really faded. It would be a great help to have a pin-out to pin-out. Also once I do this harness, is there more wires that I need to run to the mirrors also? Please help!

Just another epic fail with photobucket. They didn’t learn last time with their 399$ yearly fees...


I have the jdm power folding mirrors with USDM reflective surfaces. They’re are pretty cool. It wasn’t too hard to convert them. I’ve seen the mirrors + switch for as low as 150$. You can take your cowls off your mirrors, so you don’t have to paint the jdm ones to match.

So I can't have folding mirrors on the 01. I noticed it says 02+

I don’t know for sure...I bet the mirrors fit but the wiring is different, although that’s just a guess. I don’t know for sure.

This guide involves the 02+ USDM Lexus IS300 and the 98-01 (exact years unconfirmed) JDM Toyota Altezza with the non-heated and non-electrochromatic side mirrors.

Note: The intent of this thread is to simply provide information to those wishing to perform this retrofit; Due to the compulsory custom fabrication, a step by step walk through is neither practical nor beneficial.

The first step is of course to disassemble both sets of mirrors. The only thing worth noting about the disassembly process is in order to remove the glass mirror from the housing, pull up from the bottom of the mirror as illustrated below:



Once disassembled, you should have the following pieces:











Topics of interest:
The side mirror mounts of the JDM set are angled for RHD and will never be aligned correctly for LHD use.
Likewise, the mirror glass of the JDM set is also designed for RHD.
The JDM housing is smaller than the USDM housing which must accommodate the larger USDM heated/electrochromatic mirrors.
The USDM spring loaded mechanism and the JDM power folding motor share no mounting points.
The USDM mirror cover attaches with clips whereas the JDM mirror cover is held via screws.
The 4-way mirror motor assemblies are all identical and share the same part number.

With this information, it should be noted that there are several extents to which this retrofit could be performed. The JDM Housing and motor can be attached to the USDM mounts to achieve the correct viewing angle. The JDM mirrors can then be used if losing the heating & auto dimming functions is acceptable. In order to retain these functions, significant dremeling of the JDM housing must occur in order to physically accommodate the larger USDM mirrors.

Another approach is to fabricate mounting points for the JDM motor inside the USDM housing which will of course allow for the use of the USDM mirror and mount. This is the preferred yet most time-consuming solution. One such method in which to attach the JDM motor to the USDM housing is illustrated below:



Although there are originally 6 points of attachment for the JDM motor, I felt that the 4 points depicted by red arrows were sufficient. Note that the mounting post indicated by the blue arrow can be used to ensure proper alignment of the folding motor by attaching the 4-way mirror motor to its three mounting points before creating any new mounting points.



An area on the back of the housing was dremeled to allow the mounting of a thin piece of stainless steel to provide two mounting points. All holes were then drilled and tapped to allow the threading of screws. Also, custom spacers were created out of copper tubing to allow the screws to be torqued appropriately without deforming the housing and/or motor bracket. Note that the plastic used in the folding motor bracket is very dense and strong enough to provide a competent mount when threaded properly.

The electrical connections are fairly straightforward. The JDM mirror pigtail
connector (shown below) possess the following wiring pinout:



1: Pink w/ Green stripe
2: No Connect
3: Green w/ Red stripe
4: Green
5: Pink w/ Blue stripe
6: Pink w/ Black stripe
7: Blue w/ Yellow stripe
8: Blue w/ Red stripe
9: Gray
10: White w/ Black stripe

The USDM harness colors match exactly with the exception of a blue wire which goes to the JDM Blue/Red wire. The additional Green & Green/Red wires control the power fold operation and therefore connect to the blue & green leads of the folding motors.

Note: the auto dimming wiring is present in the passenger side mirror, but 02-03 US spec passenger mirrors do not possess this capability (unsure of 04+). Therefore, the two wires can be used to control the fold operation in order to avoid having to run additional wire. The wires of concern are Pink & Gray within the mirror unit and can also be located in the passenger kick panel, in a front 20-pin connector as the white/red (pin 8) & green/red (pin 20) wires. Splice into these wires in the passenger kick panel to avoid having to run additional wire through the passenger door grommet

Overall, the retrofit is fairly clear-cut but highly involved. Although a successful retrofit provides 100% OEM functionality and quality, I would suggest if at all possible to source a set of LHD, heated, autodimming, and power folding mirrors to significantly decrease project time consumption.

EDIT For clarification:
I've received a lot of messages from people who connected the motors to the pink & gray wires asking why it did not work. The pink and gray wires are present in both doors and are connected to the auto dim function of the rear view mirror. However, ONLY the driver's (left) side mirror of US cars actually dims. Maybe this was changed in 04+, but for 02-03 only the driver's side mirror has the white gel stuff on it that makes the glass dim. To verify, remove your passenger mirror glass and check to see if it has the white gel with the attached connector like the driver's side mirror, or simply shine a flashlight into the rear view mirror light sensor and check to see if the passenger mirror actually dims.

Because the passenger mirror does not auto dim, I suggested using the pink and gray wires on the passenger side to avoid having to run wires through the door grommet which is a huge pain. You will still need to run 2 wires from the mirror switch through the driver's side door grommet to the passenger kick panel. At that point find the front 20-pin connector and the white/red (pin 8) & green/red (pin 20) wires. Cut these wires and solder the cut wires to the 2 wires from the mirror switch. Now the pink and gray wires that are already present in the passenger side mirror housing can be cut and connected to the folding motor. This process is simply an optional time saver instead of having to run the 2 wires from the mirror switch through the passenger door grommet into the passenger door and up to the passenger mirror.
Hey I don't know if you still responded to this thread but I got a 2001lexus IS300 I have a JDM side mirror switch which I'm trying to run into my car which had the usdm switch I believe but I'm having a problem locate which wires go to what. I got a used car from the junkyard with different wires colors running from it I'll text the photos if you stood looking at this thank you

I will try to help you. But I already started on your other post. Do not double up the posts.
