Found this one that shown will fit the 2021 Sienna on Aliexpress. not sure why price different between the one labelled DRL OFF and just symbol O.

Nice find. In one of the seller’s picture, it actually explains the two fog light settings for me. The top setting is for rear fog lamps and the bottom setting is for front fog lamps. I assume the top setting (rear fog lamps) do not apply to Siennas?

I tried again today. I pushed on the clip and pulled with my fingernails but the stalk still would not come off. I’ll just have it done at the dealership. I was planning to have them install the fog lights anyway so I’ll ask them to do the turn signal stalk as well. I couldn’t fit my hand in the side of the bumper like how you did to tighten the fog lights enough. Not enough room for my hands.

I can confirm P/N 84329-0R020 is the correct part number. However, i notice its a little different from OPs. Looks like OP has two options of fog light setting instead of one. I am curious, what does both those settings do?
here is a short video shown how to take off the knob

I bought a headlight switch from the same seller, but after I installed the US version of the LE, the high beams can't be turned on normally, and it can't be used. Very sad QQ.

Does anyone know which part number to buy for the US version? Thank you

Hi Guys, I am about to tackle a similar fog light install on my 2021 LE.. I got AliExpress fog light kit, but looking at these pictures, the fog light housing uses a different connector than the OEM one that is pre-wired already in the van.

My plan is to cut the wire harness and wire my Ali Express fogs and patch into the oem wiring, and then wire the Pin 3 and 4 to my external fog light switch that came with my kit. This way I can avoid running a separate wire harness. This is all a plan for now.. I think there is also a provision in Toyota techstream that I can control the fog light relays through that.. Will investigate that path as well to confirm the OEM wiring is all provisioned.

The pin out (taken from a Rav4 model) for the signal stalk shows pin 3 & 4 is what controls the Fog lights. I cross referenced the pin out for several toyota model, and it appears they all have the same pinout and should be the same for Sienna. It shows that shorting BFG (ground) to LFG together sends the signal to the ECU to power the relay that drives the Fog lights.

I was able to complete this mod this morning. Probably best mod to do for an LE. Thank you jays3l33t

Here are the part numbers:
LAMP ASSY FOG RH - 81210-08040
LAMP ASSY FOG LH - 81220-08040
TURN SIGNAL SWITCH - 84329-0R020

Total if buying OEM from an online Toyota Dealership website is under $300.00.
(y) (y) very nice
so the LE trim got the harness pre-wire as well?

Yes. Also, there was another harness that was taped to other wires that is not bing used. Anyone know what could this be for? I only saw it on the passenger side. I do not think I saw one on the driver side.

Wild guess... Any chance it's for the OEM block heater/Comfort+ accessory option? The plug goes on the passenger side?

Update on the knob. I bought the knob from aliexpress I posted earlier and everything worked perfectly. Now I can turn all the lights off with the DRL OFF selection. The only thing is to see how long it will last.
