Try calling some yards that carry LC or LX. I called a few here in California and scored a nice 3 knob trim with the pig tails. I had to ask them specifically for the pig tails, they left a good 14" of wire on each. I think I paid $100 for all. Good luck

Where did you find this wire harness. Do you think it would work for switching out the nav I have on my 2002 LC with a non-nav? Thanks!
Just to be clear- if you undertake this Nav delete, does it then make fitting the large tesla screens possible?
I believe, Yes. You can also use other android double-din headunits as well.
Getting ready to do this in my 2002 LC. The instructional videos were done in LX. Is there any difference between the 2?
Just saw fblainen11 videos are for LC so I’ll reference those
This was the best advice. I did multiple Google searches and never came across this site (no idea how I didn't find it). When I went on Car-Part.com I was able to find a Lexus/Toyota specific yard that had a dozen 100 series LX470s locally here in Sacramento. $100 for the Lexus non-nav bezel instead of $500 on ebay.
I just finished the nav delete and I have a couple gremlins. The passenger mirror defrost, the auto and the off buttons don't work. Everything else seems to work perfectly.
The system seems to be in auto already as it respondes to the set temperature by turning to heat when I increase it and cold when I decrease it, but I can't turn auto on or off and it's light is off. The off button for the climate control doesn't turn the system off either, so low fan speed is the closest I can get to off.
I checked all the ground pins and they all are good.. The only thing I'm not 100% on is C12. It's connected to 1F, but the diagram calls it a ground and I don't get continuity between that and the body. It's not ground colored like the other grounds so I'm not sure if it's a constant ground or if it's something else.
Any help would be appreciated

Easiest method is to find someone in your area and swap the bezel. This will show you if it is a wiring issue. Do this after you triple check your wiring.
My wiring all matches what's on the diagram. Weird thing is (my own fault) I initially used the diagram from the first post in the thread. I misread something and though the first diagram was the updated one. When I had it wired that way the passenger defrost would turn on, but now it won't.
I'm going to have to go back and retrace my steps and figure out what between the old and new diagram changed that messed that up for me.
Also, it's odd to me that the bezel's harnesses have 2 wires that aren't use. It seems like this bezel is the exact one for my model (has all the same functions as my nav did).
I ordered a wiring diagram book that should be here today. I'll get this figured out eventually.
Almost done with installing my new head unit which will finish of my nav delete. I was able to locate a plug-and-play adapter for my new head unit to make use of the factory gps antenna. Has anyone used this? The connections are correct so I assume it will work.

I was going to do a Nav delete and purchased a bezel, but ended up changing my mind. I still have the Nav bezel with climate control functions kicking around. I paid $300 for the bezel with pigtails. Willing to let it go for the same price. I'll also include the antenna adapter, Metra 70-8113, double din bezel, and parking brake bypass that I purchased in preparation. $300 OBO.

Is this still available?
Is the link to the wiring diagram in the first post?
I’ve been searching thru this thread and can’t find the wiring diagrams for each harness and which wire they go into for the non nav harnesses. does anyone have them saved by chance ?
Reposting to help out people just finding this thread. (Link is broken but PDF works)
