It seems those of us with that trim have the dummy plug and the cable available, but it isn’t connected to anything at the other end.

See post #267 for SR5/SR5P's - not a 5 minute mod unfortunately...

Does anyone know if I follow the head unit removal procedure if I can reach back and get to this area?

Yes. I didn't drop the plug, but since I have an SR5, I had to run the additional wires, so I had to remove the head unit to get to the plug. I do recall having to remove the vents (or ducts) also after the head unit was removed.

Do you have a post or write up on how/what you did? Would be open to giving it a try.

Sorry, no writeup. I removed the head unit and the vents/ducts that were behind it. I just removed enough stuff to get a grabber tool back there.

I have not made any Entune menu settings like described in post #55 by @ElectroBoy yet, it seems that my menu is a bit different.

Thanks to all that have contributed to this thread, no more blinding nav screen when I start the vehicle at night.

Hey J-Dub,

Wanted to verify this was in an SR5 non premium right?

Thank you

Installed one I ordered off Ebay in my '23 ORP and it works fine. I love that I can now run with headlights on and have the buttons etc ilumited in the day, but have the display on bright. I have dark tinted windows and the buttons are a bit hard to find, even in the daylight. After this mod, the illumination makes them easier to spot .

Hi folks, I'm going to be pulling out my head unit soon for an Alpine upgrade and wanted to knock this out as well if it is feasible. I have a 2016 SR5 Premium. I've already installed the new light sensor and got it plugged into the wire that was present from the factory.

Could anyone else with a SR5 Premium who has successfully completed this let me know what steps they took that worked for them? I believe all I am missing are the pins going into the body ECU F9 connector, though please correct me if I am wrong. I purchased the vehicle with a remote started already installed.

Much thanks!

This is great, I just ordered one on ebay as well. Thanks!

I just installed an eBay 89121-30020 (~$19) into my 2021 SR5 (not Premium, just a plain SR5) and confirmed it works perfectly, no wiring required.

(and by perfectly, the gauge and headunit brightness is no longer tied to the light switch)
