As it's something that seems to always be shrouded in mystery, I've created a pair of pages for keeping tracking of part numbers for ECU and general OEM wiring connectors. ECU connectors parts in general seem to be particularly difficult to find info for and there is a little cottage industry of automotive suppliers charging huge markups simply for being able to align a part number to a certain vehicle.

Hopefully these pages might help save people a few dollars :D

Additions to these a VERY welcome, so please drop any additional part numbers here and I will get them added

OEM Connectors (WIP): https://speeduino.com/wiki/index.php/OEM_Connectors
you may want to add the Denso 76 pin connector, they are used on a large amount of makes and models
its a 4 plug connector that would also work for some miata's but you would only use 2 of the 4 plugs

part number: 178780-1

Thanks, have added it in!
The only car I know using these is the MK3 Supra, but if there are any others, just let me know and I'll add them on.
its possible only the mk3 uses it, but it can be used for lots of other aplications,

the connector consists of 4 plugs, a 12 pin, a 16 pin, a 22 pin and a 26 pin plug
a lot of japanese cars use a combination of these plugs, for instance: some miata's just use the 26 and 22 pin plug making it a 48 pin
this is beter explained in this image:(sourced from diyautotune)

there may not be a direct advantage of using the 76pin, but they seem to be easier to find in stock.

looks a lil messy, not realy a forum expert

so the cars/engines listed here will work, most of them wont populate all plugs though

this also isn't a complete list, my engine (the toyota 2E-E) is not listed and will work, it would use the 16 pin and the 26 pin

Hope this makes a little sense :)
Yeah the 76 pin version (There's also another larger one as well from memory, 104 I think, but not used much), can handle all the lower pin counts as well.

For a couple of reasons I think it's worthwhile having the specific parts for the smaller ones though. Not only do they take up less room (Eg if you're making an adapter board, you can't get the 76 pin on a standard 100mm PCB) but they're cheaper as well.

Either way, all good info :D

178764- Mitsubishi 4g91/4g92,93 sohc/4g63 evo 1,2,3. I see it same as miata, but with different pinout.

Hmmm, I'm not sure what the difference is (if any) between the 178764 and the 174518-7. Their datasheets look practically identical as far as my poor eyes can see:

174518 - http://www.mouser.com/ds/2/418/PN_CD_17 ... 243432.pdf
178764 - http://docs-asia.electrocomponents.com/ ... f8d181.pdf

BTW, for anyone wondering, the number after the hyphen in the TE/AMP part numbers is simply the revision. Eg 174518-1 and 174518-7 are the same part, -1 is simply the first version and the -7 is the 7th. Usually the differences are minuscule and make no difference in the application, but searching by a lower revision number on parts sites can lead to them saying it's no longer stocked, even though they might have the newer revision in stock. Just something to keep in mind when searching.
Apparently this is not the case for all of their connectors and so shouldn't be relied upon.
