Wiring diagram
Hi fellow Lexus lovers

First post on here having owned a number of Lexus vehicles so be gentle 😊

I have power mirrors on my IS F-sport 300h 2014 model and miss the automatic folding on my previous RC. To rectify this I have purchased 2x kits that can be connected to an existing power mirror circuit. The kit was manufactured in China so the wiring diagram isn't exactly intuitive and the terminology such as "signal" is ambiguous, see the attached diagram.

I'm pretty confident with auto electrics but wondered if anyone could advise on the wiring for the following in the door looms:

• Output for opening mirror
• Output for closing mirror

• Door open signal

• Door close signal

I can a meter to identify ACC ON and a constant 12v feed but if anyone can advise that would be appreciated.

Thanks in advance.

That’s a awesome idea, never knew they sold kits like for folding mirrors. Where did you order them from? Welcome to the forums as well, sorry I have nothing informative to add, just an additional question.

Thanks for your reply and welcome to the forum. I bought these cheap from eBay, see item listing - eBay Item - AUTO Intelligent Car Auto Side Rear View Mirror Folding System

I'm guessing youre going to install everything down in the driver side foot well area. There is a fuse box under there that has many different sources of power. I'd suggest getting a pair of Add-A-Fuse's to tap your wires into there. The fuse labeled HAZ is a constant 12V and IGN1 is a switched 12V (Comes on with ACC Mode).

That looks like just a little chip for if your mirrors ALREADY have motors in them. this just makes it so it activates upon parking or something like that. it's not what you guys are thinking.

Hi there, each kit will need to be fitted in the actual door so once the door furniture is removed the box needs to be secured in place and wiring tapped into the correct connections.

Dang! You’re right, after checking the product link I realized that...sure wish our vehicles had the auto folding mirrors. I was amazed to see a Kia Optima with them and to know it wasn’t an so much as an option on mine. 🥺

The automatic feature is available on specific models, the Premier which leads me to suspect fitting this kit should be straightforward.

Door open and close signals seem to be for the door
lock actuator. I’m guessing when the door is locked, the mirrors will fold closed; when unlocked, mirrors will fold
open.

Perhaps the mirror open and close signals are what drives power to fold the mirrors open/close based on the door locked/unlocked signal?

That's a good point, the instructions mention that the mirrors will function with the door locks or it does have "smart" technology for when the ACC is turned on. My concern would be that the doors lock once taken out of Park and I wouldn't want the mirrors to fold then. As the button to fold the mirrors is a press and release perhaps that's the signal that is replicated by the kit, I have a feeling this will be a trial and error exercise and hopefully I'll be able to share the guide for installation for the everyone's benefit here.

Cant be sure, but maybe they meant to write “ACC On Inhibit Input” meaning to prevent automatic operation when ACC power is supplied. Just a guess.

99.9% of the cars on this board are US models. Since we don't get power mirrors on the IS, this little $5 chip wouldn't apply to us.

Sadly the motor mechanisms themselves probably cost next to nothing for manufacturers as little cheapie cars in the ROW come standard w/ such mirrors. But Lexus charges a ton of money for the parts retail.
