I just saw that, I had to answer the phone so you and Fab beat me to it. I may actually try that one though, for my application it looks overkill. Me likey overkill.

It's also like $35 cheaper than the one I posted. Me likey cheaper

 

Wait a sec... the RCS-027 bulkhead thing says this:
Racetronix - Connector, Fuel Bulkhead 4-Way 280/150

That makes me more than a little nervous. Is this "keyed" or something like the universal one I posted earlier?

 

Drat, no it needs another piece we dont have I thought it was included because it was shown on the technical drawing, but it isnt. But the reference on the drawing seems to have enough detail that you could get that part made up.

 

Thank you for the generous offer! Where can I paypal the shipping fees?

RATS! There is no retaining clip and it looks like it needs another harness of some sorts on the bottom of the bulkhead connector.

Did anyone ever find a Sumitomo DL 090 4 Position .090 Sealed Male Connector in order to adapt the NB CMP and CPK sensors to the NA CAS harness connector?

 

IT DOES NOT EXIST, CONFIRMED BY SUMITOMO.

If you want one, order 100,000 connector housings for it from Sumitomo.

 

Random thought:

A few people on this forum posses the ability to individually 3d print hard-to-find connector housings out of ABS plastic.

Would they include the same rubber gaskets as OEM? No. Use grease.
Would they prove to be as resistant to heat and mechanical stress? Good question.

 

The CAS side connector doesnt even have a seal, thats on the harness side. And if it was made correctly you would just use the Sumitomo DL seals for the terminals. I'm not going to model the connector up in cad and try to make it actually functional when made in a 3d printer. Getting the terminal retention system to work is going to be a massive bitch and might even be impossible on current 3d printer tech.

 

Since I got so much info from this thread.... I thought I'd contribute.

I sourced the 01+ Coil near plug connectors from Ballenger motorsports part #CONN-85775. These connectors make a good connection but they do not seem to clip into the coil near plugs like the oem connectors do.

At any rate... All I did was throw a zip tie around them to make sure they are held in and don't vibrate loose. They still work like a champ, however I'd suggest to others that it may be better to try and find OEM connectors to splice in if you're looking for 100% oem operation.

 

The OEM ones that do clip on are just sumitomo DL 3 position connectors.

 

well... then they changed the mold or something since they were used in the miata. I have qty 2 oem connectors that were cut out of an 01+ wiring harness and qty 2 that I sourced from ballenger. The ballenger ones do not clip into the coils and the OEM ones clip in perfectly.

I did realize they were the same connector by reading this thread... that's why i bought them and assumed they'd work perfectly. Which is why i'm posting that I was surprised so I could pass on my experience.

 

Hmm, the ones I got from eastern beaver were fine.

 

So Weather Pack connectors it is then for mating the NB sensors to the NA harness. Thanks.

 

The OEM connectors on my 2001 do not click into my coil packs. They are a very tight fit though and it has not caused me any issues.

 

Any info on the pin part number for the diagnostic box on 96-97?

 

I just ordered those but can't compare with OEM that I don't have... and VVT connector as I saw EOK post too late.

Will try to give an update in few days.

 

On that subject- here is a functional beta connector for the NA8 MAF male side:

1.8 miata MAF connector BETA by AlecMoody on Shapeways

What are people's thoughts on buying one off connectors? That $11.64 is cost from shapeways. If they were cost + $5 and you had to add your own pins would people order them?

Can anyone make a quick list of which connectors are the most in demand? I could add weather sealing to these connectors but it would be expensive since it is a lot of labor to make tiny little molds, degass and then pour a half oz of silicone.

 

I would've paid $20 for the male CAS connector.

 

Also, does anyone know where to source terminals that are compatible with the OEM sizes? The delphi 280 series I am using is a really bad fit in the MAF connector and I can't find anything with the OEM dimensions.
