Turn Signal Control Unit Connectors

[Wallowgreen]

I'm trying to source some of the 4 and 6 pin connectors used on the turn signal control unit (or at least on the one in my '79 GS850G). I don't know if these units are standard across mulitiple machines or not but from what I've read here at the resources it seems like they cause enough trouble.

I have a problem with mine and was amazed at the sticker price for a new unit. Being an electronics design engineer with a large international blue chip company who designs embedded microcontrollers for them, I figured I'd design and make my own replacement unit, keep the money and have some fun at the same time. Right now I have a fully operational prototype system and am about to design a circuit board for the target enclosure so it'll fit nicely in place of the original. Next problem will be to get some original connectors to make it an easy install plug and play unit. I've looked at the connectors on my unit but can't see anything to give me a hint who made them or where I might get some, even under a microscope! I've also spent a few hours trawling the internet but without anything to go on that's kind of tough.

Does anyone know the manufacturer and part number for the 4 pin and 6 pin connectors on these turn signal control units? Or alternatively where I can find out? I presume they're the same on all of them.

Can anyone help with that?

Perhaps you can find something that will work here:

Go to the "order" link to see/buy individual connectors. I've bought some stuff from here once & had no problems getting it - came in the mail very quickly.

Thanks so much for this pointer. I think I may have found a workable solution from these people. Turns out they seem to be Hitachi connectors after all but of a different type. Vintage connections had something that looked the same except they now have a locking mechanism. They are for 2.8mm spade type terminals, I measured the one's in my unit with a micrometer at 2.75mm - close enough.

Ordered two sets of both the 4 and 6 pin type today. Even if they won't plug directly into the harness, the spade terminals should fit into the new shells, which come as a male/female pair. That should make fitment pretty easy, no crimping or soldering just take the spades out of the old shells and put them in the new.

Thanks again for the help.

Yes, I pretty much did the same - removed the existing spades & re-inserted them into another "undamaged" connector shell.

I've started keeping all my old electrical plug "shells" as spare parts now just for that use. You never know when you may need to repair/replace some connection.

Good luck with your connection fix, let us know if it works out.
