[info] 64 pin 176122 ECU connector board

[AndreyB]

I've realized that we do not have a thread for the 176122-6 connector board - this board was finished before the forum was created.

Just to confirm that this board fits well with my 1999 MX5 ecu plug type.


For the 12v power pin (on my car ecu pin 1B) it would have been nice that there were more than 2 connection points on the connector board.
In my case I will need several power wires using the 12v connection including the 12 to 5v power supply, high side ignition driver feed, vbatt , alternator control, map sensor etc. It is unlikely that the ecu power pin will be the same on all applications so it probably not possible to have a universal solution. What could work is a separate break out area on the connector with say 5 connection points in a row that can be connected to where ever the power pin is via a wire jumper. A similar ground strip break would also be nice.

looks very neat!
this connector was natively used in this case? or it was just a lucky strike?

[AndreyB]

I've learned yesterday that 1994 Toyota Camry 4 cyl uses this same connector.

[AndreyB]

Applicable to same vehicles as AEM 30-2983C - see the list on Amazon

Honda 4 cyl 1990-1995
Mazda Miata 1990-2000

By the way the connector itself is available @ http://www.onlinecomponents.com/te-connectivity-amp-brand-1745187.html?p=10263869

The 48 pin sibling of this connector is 174917-1 available @ http://www.onlinecomponents.com/te-connectivity-amp-brand-1749177.html?p=10264022

[AndreyB]

can we please add the silkscreen to match the mazda ECU pinout? We can make the board up to 50mm tall so that we can use the extra space for the text

[AndreyB]

A more important suggestion would be to make the holes for the wires larger, the size we are using on all newer boards.

[AndreyB]

By the way the new plugs are

I ran into a bit of an issue when building a harness for an NB1 recently. I was using DIYAutotune's harness wiring and a Rusefi 64 pin breakout board. To get the stripped wires into the holes on the board, I'd have to remove strands. When I used an NB2 breakout board, the holes were plenty large for the wiring. Is there any way the next production of NA6/NA8/NB1 breakout boards can have larger holes?

[AndreyB]

I know what you are talking about exactly. Yes, current published getbers have larger holes and I've placed an order for a batch couple of weeks ago, you reminded me to go check when would I got those.

[AndreyB]

New version of the board has arrived - better silkscreen and larger wire holes. https://www.tindie.com/products/russian/ecu-64p-connector-bare-pcb-honda-miata-nanb1/

Old version on top, new version on the bottom.

[AndreyB]

If we decide to make our harness 175061-1 would be the smaller terminal (starts at 0.05$ in US) and larger one is 173631 (starts at 0.02$ in China or $0.20 in US)

Has anyone crimped these? Does it require a $200 tool?

[stefanst]

I've used needle-nose pliers. Not pretty, but: so far, so good.

[kb1gtt]

Poor crimps have a wide array of problems, which can range from electrical fires, to high voltages which damage chips, to simply getting a wrong signal. I suggest following the MFG's crimping suggestions. At work I've seen what happens when you do not use the proper crimp tools. See page 3 of the below PDF from TE.
https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Specification+Or+Standard%7F114-8005%7FB%7Fpdf%7FEnglish%7FENG_SS_114-8005_B.pdf%7F176122-6

Also on that PDF, from page 15 to half of page 18, there are several crimp tools noted. AKA they have like 100 different options, and getting the proper pin for the proper application is as important as doing a proper crimp. If you are considering making harnesses, I would suggest picking a gold plated pin which can handle at least an 18 awg wire from those potential reciprocals. Then get the official crimp tool for that pins. Notice they list the crimp tools for each of those pins, and there are like 20 different crimp tools. The below looks like a receptacle crimp tool which covers a wide range of crimp devices. It's about $400, others were more expensive, some wore $1k+

Hmmm, how to find the receptacles. that seems to be the key problem with this connector.

[AndreyB]

It's about $400, others were more expensive

$50 is the threshold. https://www.amazon.com//dp/B078WPT5M1 has positive reviews.

[AndreyB]

Damn https://www.amazon.com/dp/B019ARWWFY has three versions how do we pick which one is most relevant for us?

[kb1gtt]

Do you know which socket you are trying to crimp yet?

You will more likely get a better crimp if you try ordinary pliers like previously mentioned. These are simply limiting your abilities to make a crimp.

[AndreyB]

Do you know which socket you are trying to crimp yet?

TE 175061 and 173631 as mentioned before.

[kb1gtt]

I missed that in the prior post.

I see several options found here, for the 1mm wide tab receptacle with different AWG or MM^2 sizes.

Wow these 90302-1 are $800 new and you can find (old ones?) used for under $50.

[Neobob22]

hello and first, congrats for the job !!

you'll know that Miata use 2, 3 or even 4 connector like that :


finally, i'll just need the 64 pins you done to connect my standalone ECU to the 96 harness of my Miata, but as I want to also add sequential spark and other sensor/switches in an out, AND it would be a benefit for your product to adapt to most of miatas, is that possible to make the same board for 76 pins in 2 rows like the TE 174915 here below ?



thanks

[AndreyB]

you'll know that Miata use 2, 3 or even 4 connector like that

which Miata uses 76 pin / 4 plug connector?

[Dron_Gus]

Subaru were using this kind of connectors up to 1996. Including 76 pin.

[Neobob22]

MR2 turbo also and other toyota, sub, ford etc

you'll know that Miata use 2, 3 or even 4 connector like that

which Miata uses 76 pin / 4 plug connector?

you're right, NA use 2 or 3 plugs depending on year, then NB1 3 plugs and finallyNB2 use 76pin but its a different shape like you have already done, in 3 rows !
i've been mistaken by https://www.diyautotune.com/product/diybob-breakout-adapter-nippondenso-76-pin/

with that in line, would you consider to make the breakout board for denso 76 pins 4 plugs connector in 2 rows like that or no interest ?

thanks !

[Neobob22]

i imagine it's a no

[AndreyB]

New version of the board has arrived - better silkscreen and larger wire holes. https://www.tindie.com/products/russian/ecu-64p-connector-bare-pcb-honda-miata-nanb1/

Code: Select all

 1) RESOLVED IN R0.2  Silk screen was made better. 
 2)                   Add same silkscreen to back side.

[TurboTurd]

Hi all,

I have found a seller on eBay selling a version of this board, that I wish to use in my Mx5 ecu build.

Could anyone tell me what the layout of the 'output' pins on this board are for? I.e. what is the intention for connecting this to your main ECU board? Other adapters I have seen for different ECU connectors use a standard 40 pin IDC connector for this purpose.

Thanks

Sam
