Hey, I'm trying to figure out the pin out for the blue square connector in the '99 NB engine harness, I think it's called the X16 ( X-16 ? ). It's located near or on the heater assembly and has that green security latch. I looked in the factory FSM posted here and the Mitchell wiring diagrams that were on another site, I even looked on Motor Alldata. I found pin out diagrams for wire connectors that engage components like the ecu, but no pin outs for harness to harness (mid harness?) connectors.

I'm installing stand alone megasquirt and a new engine in My '99 so I need the info to hook up the stock guages and what not. I'm selling my 99 engine and trans to a kid with a triumph project and it would be nice to give him the info he needs to utilize the wiring I'm selling him.

Can anyone help me find this info? Thanks.

 

This one?

 

 

That's the one, Thanks Joe. I didn't see them in the FSM from this thread https://www.miataturbo.net/useful-sa...34/#post889636

Is there a seperate manual with wiring diagrams or was I not looking hard enough?

Everyone has been super helpful around here. Hopefully at some point I can answer questions instead of asking them.

 

For the NBs, the wiring diagram is separate from the FSM.

 

Joe, do you have a link for the wiring schematics? It will probably be something I will find useful in the future.

Thanks

 

I saw this thread and the first thing I thought was, "I bet Joe Perez will be the hero here."
Sure enough.
You're the man, Joe Perez!

 

2000 MY wiring diagrams located at the bottom of the page here: Miata Information


I don't know how I didn't find them! I searched for almost 40 minutes last night.

 

Sorry I didn't get you that link- I'd been working off local copies. But yeah, that's the version of the diagram I have as well, and from the same source.

I'll never understand why Haynes / Mitchell / Chiltons / etc even bother publishing wiring diagrams. They're complete rubbish, and I have never seen one that didn't contain at least a few errors.
