Auto dimming dash lights
I wanted automatic night dimming dash lights as described in this thread:
Dear Toyota, please fix this in the next production year of the 4Runner
So I ordered a light control sensor from eBay for under $13, including shipping. I made sure it was from a US distribution center so it would ship quickly. It’s a Chinese knockoff, but it has the same part number as the Toyota OEM. 89121-50020. If you look on Toyota websites it’s listed for around $120. That’s nuts; it’s a simple photo sensor.

I carefully pried off the black plug on the front of the dash near the windshield. There’s a small electrical plug attached. Take it off and plug in the real sensor. I tested it before snapping it into the dash. With headlights on and the dimmer switch *not* clicked in the full bright position, by covering the sensor then shining a flashlight on it, I could demonstrate the light dimming action. Then I seated it fully into the dash.
Works well, I like it.
