i stumbled into a bunch of what maybe honda 4-wheeler parts.
these are new, in the bag or box, and each have factory part numbers on them.
after an exhausting search on the google, i can't find a thing ! nothing even close.
i'm sure these have superseded numbers, or maybe these are not available anymore, but as popular as anything honda is, you would think finding out what these things fit would not be a problem ?
i even tried the bag and amazon, but no luck.
any ideas ?
a big TIA for those that can help !

Have you tried any Honda 4-wheeler club sites? They might recognize the parts.

Can you post a few of the part numbers please? And maybe a photo or two of the packaging and part numbers and I'll see what I can find. I have a few close friends that are longtime Honda dealers.

Don't need a gray haired old parts person if the part numbers are correct. I have several mid and late '60's Honda motorcycles and I can still find parts info for Honda products and items from part numbers or descriptions. They are really, really good at vintage parts and info so much that even young parts people can help.

The 1984 TRX200 – The first Honda four-wheeler
Honda’s research made it clear that the next step in the ATV’s evolution would be another wheel. Thus Honda’s first four-wheel ATV, the TRX200, debuted in 1984.

Not only Honda's research, but a number of attorneys made 3-wheelers obsolete.
FWIW, most Powersports & Motorcycle dealers are open Tues-Sat, if the info can't be found online.

wiring harness : 38370-SA5-8101
relay [?] : 37300-PB2-811

just a couple of things.
the reason i think these are 4-wheeler parts, is there is a license tag holder [new, in the bag, but no part number on the bag] the size one [or possibly a motorcycle or scooter] would have, and the storage building owner these parts came from said there was a 4-wheeler there at one time.

Are you sure these are not Honda automobile parts? What color is the print for the part number and packaging? If it's blue it's for the auto parts, and red for motorcycles/ATV.

Usually the part number prefix numbers identify the category or segment and when I did a search for the first part number you listed it came up with an automotive part. Genuine Honda 38370-SA5-671 Power Window Control Unit Unless you know of an ATV with power windows I'm guessing these are Honda auto parts?

The other part is a thermostat for a Honda car also https://www.hondapartsnow.com/genuine/honda~thermostat~unit~19300-PB2-811.html

Honda car dealerships have blue HONDA signs and Honda motorcycle dealerships have red HONDA signs.

i wondered about that as well.
however, the wiring harness is in the bag, and it has red lettering on it.
the other gizmo is in a cardboard box, and the box has the "honda genuine parts" sticker [with the part number on it] which is red.
the tag frame/mount piece is in a bag with red lettering.
there is also a sealed bag with two relays in it, but no part number. that bag also has "honda genuine parts" in red as well.
i'm guessing the relays go with the harness.
everything bagged or boxed have red lettering or tags, so this really makes one wonder how old this stuff is, or why the colors of the lettering seem to be wrong.
i thought i had pictures of this stuff, but i don't. i'll have to get the camera out. [i'm the only guy here that don't have a phone. ]

There is a guy here in Michigan that is a Honda CT70 hoarder. He would more than likely know. Look up his site. Vintage Honda Mini Trails. His name is Gary.

thanks Jonny !
