I got a crazy out side the box idea today. I emailed Yosh and asked them for the mfg, part number of the plug. Be interesting to see if I get a reply.

RidgeRacer · Guru

I talked to someone today who said that they had actually tracked down the mfg of this plug but through somekind of non-competion / exclusive sales arrangement with the bike manufactures refused to sell them.

So it looks like its time for plan B...soon as I figure out what that is.

How does Dynojet get connectors for their Power Commanders if that configuration is proprietary?

Are the pins you're trying to access in the ECU currently unused (unpopulated) in the OEM connector? If so, can an auxiliary harness be built that would essentially add a service connector to the stock harness using the OEM connector?

It was unclear from your posts if you're looking for the connector or just the pins. If you're looking for just the pins, K&L Supply sells terminal kits that contain several types of Japanese proprietary pins, which are also available in bulk once the right one is identified. See http://www.motorcyclecarbs.com/kl/catalog/2003/104.pdf for more information.

BTW, you mentioned that this is the same plug that the Yosh box uses. That would mean that it's the same as the Teka SFI plug, which is available to the aftermarket, apparently.

Sorry for the confusion I sometimes forget that this is a new site and everyone hasn't been following along for the last 6 months.

The bike harness has a female plug located in the tail, left side, next to the terminal you short to get the FI error codes. Its all wired ready to go.

The plug shown above I got from Kawasaki (part # 26011-1773) It has no male pins. It is sold as a dummy plug to keep the bikes plug clean and dry. I don't know if every bike has the dummy from the factory or not. If so than everyone who owns a bike already owns a plug shell in which case we are really just looking for the pins.

This is actually getting a little silly. If I just had 30 minutes with the bike I could answer a whole bunch of questions. My friend sold his ZX-12 the day before I was suppose to go look at all these connectors. If I could just get my hands on one I'd measure its dimensions and then surf the catalogs finding a pin that would work.

What I would really like to know:

Is this the same plug as a DynoJet PCIII? Some have mentioned it looks the same but has anyone actually plugged a PCiii plug into the MAD port in the tail to see if they physically mate? (with the PCiii power removed, bike key off, etc. of course)

Do the bikes come stock with the dummy plug installed over the MAD port?

As for being proprietary I emailed Yosh and got no response. When you mentioned the TEKA I called FactoryPro and a someone there is the one that told me they found them but couldn't buy them. He said they make their own. I haven't tried DynoJet because no one has proven to me yet the PCiii plug is the same plug. A suzuki user group that has had a thread on making your own Yosh box knock off for over a year and non of them have found the plug. They make their own by shoving pins in the empty shell that comes with the bike. I tried emailing the guy with their pins but he is in germany and I got no reply.

At the last site I even tried to get 1 thousand users to send me $10 each so I could just go buy a research bike for this project.

No luck their either

The saga continues....

I can post some photos of my Suzuki service port and my Teka SFI, along with the pins, if you think that will help. I can also try plugging my Teka SFI into - gasp - a ZX-12 to make sure it fits.

Photos will have to wait until I can do natural-light - the flash kills all of the detail in macro mode... I was able to match the pin types in the Suzuki wiring harness to the FRS-101 type, though. This is a commonly-used pin that's used throughout a 2000-2003 GSX-R750 wiring harness.

At $3 for a pack of five, this might not be a bad place to start. If you like, I can order up a 26011-1773 shell and a couple different pin types and see what I can figure out.

RidgeRacer · Guru

If you would be willing to do that it would be a big help.

I could order the pins but even if I found out they fit the shell I have no matching female connector to try the pins in to make sure they are thick enough to make good contact.

Hey RR

Give me a call today ***-***-**** Let me see if I can plug the pc3 into the interface plug..

Please don't post personal phone numbers in the threads

I've finally identified the 'Yoshbox' plug pins. They are made by Sumitomo, part number M(1500-0105) or M(8230-4408).

Drawing

I still don't have a partnumber on the shell except that I know you can get them from kawasaki for $5 (Kawi part # 26011-1773)

The chances of getting the pins from sumitomo are slim and none. I'm trying to buy some surplus online from places that help manufacturers dispose of excess or discontinued inventory. They are sold on 5000 pin reels so I may end up with a lot of them.

Better late than never: I finally got around to matching up the Kawi part # 26011-1773, with the FRS-101 pins installed, to a ZX-12 wiring harness. Indeed, the FRS-101's are the correct pin. They can be ordered from any K&L dealer or through various internet sites.

The coresponding female pins are FRS-102 and the seals are FRS-103. Note that proper installation requires special pin-specific crimping pliers.

Thanks for finding that out. It is still relevant as the busa, gsxrs, and other bikes all use that same 'yosh' plug. For all those bikes rewiring the yosh plug to be a reflashing plug is probably the best way to provide a quick reflash connection to the ECU.
