The Atlanta.Lexus link provides wiring harness loom P.N.s but am simply looking for plastic clamps.....
Images below depict various types.
Does anyone have correct P.N.s???



Dismembered plastic hole insertion clamp showing lances.





Remainder of wire loom engine harness plastic clamp on driver side at intake manifold.





Push-on bracket clamp showing 10 mm inner diameter marking.





The black wire harness clamp is correct. Lexus is offering the incorrect part in brown.

8271150310 clamp $4.64

Like I said for the 1st link. Those pictures are the same ones the dealer would pull up if you go there to order
parts. The parts books will have the clamps, just hunt for them. Yeah that brown one is way too big. But it maybe an updated part number and part ! This is a good example of where a 3d printer would be nice.
The other option is a wrecking yard, shame they aren't pulling up the right part.

Every LS400 previewed has brittle-decaying; engine wire harness plastic wire loom clamps, plastic connector shells, corrugated and vinyl type engine wiring harness sleeves. The wiring and connector contacts are typically in good shape, but require recovering. This would present an opportunity for kits, however the last time this was posited to me for rubber bushings received a stern warning from the site administrator about soliciting or polling for the purpose of conducting commerce. I have a complete plastic connector shell P.N. list for 1998-2000 LS400 (overlaps to 95-97) and 2001-2006 LS430. (NO chopping off old connectors to splice in a pigtail...the contact lances are compressed with an appropriate probe and easily extract from the plastic shell) Let me know if anyone requires assistance.

Yeah I forget the place its supposed to be, but we need it here some place for LS specific stuff, lots of us can get lost or never know where to look. Especially older not so computer literate folks, and that's why they ask a question and never come back for the answer.

I agree. I've got a Lulzbot TAZ5 3D printer at work, and have been thrust into the role of 3D printer guru by my coworkers. The more I learn how to work that beast, the more I see me printing these sorts of parts for my LS as needed. The hard part is getting precise measurements from existing parts to feed into the 3D models for replacements.

Just use some good digital calipers for the dimensions. Also I think there are 3d scanners now too.

Sure, but until you actually do it you don't realize just how many measurements are required. The clamp pictured by YODA would have no less than 30 dimensions, for instance. 3D scanners are not yet up to the task, btw. Maybe in another 5 years or so.

Machinist here. So I do. This is the kind of 3d printing I was exposed to about 10 years ago. Stereo Lithography
It was similar to this only a larger vat of resin and you could see the lasers making the part. These are what you would want as its not so rough a finish.

Not opposed to trying new things... These parts however are not unique to this LS400. Somewhere, someone in the World of Toyota has correct O.E.M. P.N.s and, or, parts. Seeking that information. Thanks.

Yeah and kind of maddening when you know they made millions of those. I wonder how many dealers toss out obsolete parts, you know taking up space and inventory taxes etc.

So persistance pays off...

The plastic wire harness clamps have a part number stamped on the shell, much like the plastic wire harness connector shells.
Part number prefix is usually 82711-

7mm wire harness clamp molded with part number 3H380, so Lexus part number is:
82711-3H380

82711-3H380 is used in at least 3 places on 1998-2000 LS400..here near throttle position sensor (it did not come with the spongr rubber spacer....)
Location #2. Same plastic conduit atop throttle position motor
3rd location at airflow sensor corrugated wiring conduit... This plugs into the air filter box...sometimes the plastic receptacle hole is broken when an over-anxious mechanic forgets to unlatch it before removing air cleaner assembly. .or wores, they damage the wiring
Images of new parts and part number. McGrath Lexus assisted with sorting out part number
