Evening peoples.

I need to run my IAT into my loom for my MSPNP.

Rather than do this



And wrap the thing in 3M lecco tape, I am looking for a neater solution.

I have been thread mining and found the connector witch hunt thread
https://www.miataturbo.net/general-m...t-70034/page8/

Looks like we found that a 95 MAF plug is a "Yazaki 2.3II(090II) Connectors Sealed 5 Position Female Housing [Black]
Part.Nr. 7283-1056-30"



So did some google fu and I THINK this guy
https://www.bmotorsports.com/shop/pr...oducts_id/4326 is a winner as a solution. Can anybody who is more skilled in the art of plugs and shizzle confirm that this bad boy may well work to splice in with my IAT sensor?

Many thanks

It looks sooooo close but not quite right. Here's a photo of my '95 MAF housing. Looks like the pins are located differently with reference to the two keys. Not sure it would work, although maybe there is enough play in the pins.

I ended up inserting a 6 way Deutsch plug to make the MAF connector a sub harness. I'll replace it with a new sub harness that connects to the IAT sensor. Also allows for an easy return to stock if required. Like you, I wasn't keen on the stick in, bend and tape method.

Nice. Didn't consider cutting the car loom.

I got impatient earlier today and ordered one of those plugs before I saw this reply, along with some crimps and other connectors for WBO2 connection from Ballenger. I will try it on the MAF plug when it shows up and if it doesn't work I can try fiddling/dremeling with it or do what you did and make a subharness and write off the 7 or so bucks

Thanks.

Why don't you run the 2 wires to MS and eliminate the harness for MAF.

Zaphod

The OEM connetor to the MAF is a "wire-to-device" connector- which implies that there always is a physical device connected, no other connetor (male/female) - so there is no mating part for that...

I could run wiring to the MS, but is a PNP and there is already a harness running to it. Didnt't really want to overcomplicate things and to retain the ability to return back to stock ecu if I move somewhere requiring emissions testing which could well be on the cards.

Have you checked the Miata specific page on Ballenger Motorsports?

No - didn't see that but it is bookmarked now!

Thank you!

stevos555

You have an open port for an optional connector on the other side. The connector came with the unit for you to build more direct accessories to be wired in. No splicing of OEM harness will be required.

stevos555

There is a post under MSPNP section asking about crimp connectors. You can see in that post the connector that I am referencing.

msmola2002

Ok. Took a while but finally got to play with this.

the plug from ballenger https://www.bmotorsports.com/shop/pr...oducts_id/4324

mates up. My IAT is mounted in the crossover pipe near driver's headlight so is a short harness. If this thing ever goes turbo I'll just make a longer one, and for ebc will just add to the pins.

No running of wires from behind the car to behind the seat, no cutting of loom.

pretty neat solution!

stevos555

Do you have part numbers for the plug? I am doing the same. Is the pin 3 and 4 the same for 97?

msmola2002

photo in here MegaSquirtPNP by DIYAutoTune.com

is the same as for 94-95, so I'm assuming yes.

plug is here

I also bought their weatherpack crimpers
https://www.bmotorsports.com/shop/pr...roducts_id/362

they work nicely and the wires seem quite secure. I'll never go back to regular spade/bullet crimp terminals.

thanks man!!

When I was looking to extend the MAF cable in my car I found this extension on ebay. Says it's for a Toyota but it worked fine in the Miata. When I put the MS in I just took out the extra wires and soldered the ends to the IAT sensor. I can always put it all back together if needed with a little soldering.

I see EBC in the thread title...can you use the other MAF wires for an EBC add on to MS? That is, can I route the IAC and EBC using the MAF?

Thanks.

Yes, its in all of the MSx info that's related to Miatas, like: https://trubokitty.com/#/installation

That's the same as what I did with my NB IAT

Except I used **** connectors rather than fancy OEM looking ones (no way in hell I could work out how to crimp the IAT plug things without them just snapping off)
