Does anyone know if it's a simple swap to go from XLE Premium headlamp assemblies to the SE version with the LED DRL? I really like the look of the SE's LED strip but I'm unsure if my XLE has the proper wiring already in place to make it plug-and-play. Thanks for any help you can provide

Thanks, that's pretty much what I needed to know. I don't want to get into a complicated mod just to have the LED look.

If you just bought it new and liked the look of the SE better, why not just get the SE? Is there a big price difference between the two? Is there some other drawback to the SE?

In my area there was only 1 SE Premium in PNB and they weren't budging on price. The dealer that had the XLE Premium in PNB dropped the price considerably and it had the extras we wanted already installed so it was an even sweeter deal.

So I was the one who did the not-at-all simple conversion of running 2015 SE headlights (first year of the LED strip) on my 2012, where none of the connectors existed to power the LED strip. I think that my situation was made difficult because the headlight harness pre-2015 didn't have LED strips on any models, so I had to splice the various wires myself. I think it's worth investigating what your headlight harness looks like, and comparing it with online photos of a post-2015 SE's headlight, the main thing being the 2x2 connector that powers the LED strip. Toyota has shown that they sometimes use universal harnesses across trims, like how the rear windows can be converted to motorized ones by just installing the motors and the switch. Maybe yours has one too?

Unfortunately, there are still different engine compartment main wiring harnesses for variations of the Sienna with high beam DRL and LED DRL. It's puzzling that there have been at least two revisions of the part numbers since 2015 but maybe that was related to the revised 2018-up front end designs. The part numbers can be viewed at https://www.toyodiy.com/

Thanks for the input! I checked and there is no extra connector that I could see. I checked the fuse box and there is a large marking for "DRL/DIM" but no corresponding flasher/relay/fuse/etc in the actual fuse box. I was hoping I could get the LED look, darn.

I mean... you still can, using my not-at-all simple way. I think there are also aftermarket headlights that are plug and play -- that's what those VK builds seem to use. You don't have HIDs, so the projector should be good enough.

If you are mechanically inclined and electrically confident, its an easy conversion, IMO. Like Graure mentioned, it takes some time to tap and solder wiring.

I was planning to get a pre 2015 as a MOD car and planned to do a full modern conversion. My wife doesn't want me to do too much to her 15 SE.

I was looking to some $450 aftermarket version and doing a projector retrofit so it was perfect platform vs. $1,200 for OEM 2015. https://ebay.to/2rOo5BL

You can also try the DT Moto aftermarket housing...not OE look but close and a deal at $260 or less on eBay- https://ebay.to/36F4cMt

I saw some OEM on eBay via two OEM Toyota parts liquidators for $200 but only the LH light, no RH light left.

Awesome info, thank you. I'm going to reach out to the ebay seller and see about getting a pair. Do you have any guess as to why it lists only the 2014-2017 SE as the compatible model?
