Who make/made the wiring harnesses for late 1990s Yanmar 3JH-2E powered Hunters

[Diablito]

I've read multiple forums about the endemic intermittant starting problems. It seems that it is very rarely the starter.
I've read of several "work around" fixes. I've done one of my own, but I'd really like to find out what company provided the 3 multiple pin plugs/wiring harnesses. Was it Raytheon, because all of the instruments are theirs? How about Yanmar, because it's their engine? Some other entity, entirely?
It seems that whoever it was would have debugged the problem, over the last decade. If not, they should at least sell them.
Thanks to all of you equally frustrated owners.

Don't know that exact engine specifically, but Yanmar typically provides the engine unit complete with wiring to Hunter .. The wiring and connectors are shown in the Yanmar shop manuals. Mine has 10 wires in the connectors so something like this could be used for replacement .. either a 10 wire unit or two 5's.

Kloudie1,
Thank you.
My Yanmar 3JH2E has 3 connectors.
I have the manual, for the engine. I'll review it, again. But I doubt that I missed it, since the problem has been making me nuts, for awhile. And I've tapped into Yanmar, on line, too.
Again, thanks.

It's a Yanmar harness
Yanmar supplies a harness to Hunter which is typically too long, so they coil up the excess.
Raytheon has nothing to do with the engine wiring.
The intermittent start problem is easily solved with an inexpensive relay. This has been documented on this site many times.
Long story short, if you do this, your problem is gone for good.

The other solution is to run new wire to and back from the engine controls. Or to clip the wires on each side of the connector and insert a small like 3-4 inch piece of wire with butt joints. I have several wires through the connector. The temp oil senders, the tach, etc all go through. Though those shorting now and again isn't nearly as irritating as the starter not working.

Thank you.
I installed a relay last Saturday. So far all is good.

To everyone who helped, or tried to help, Thank you.
For the next victim installing a relay is a good idea, before buying anything else.
I bought these items through Amazon. Part numbers and prices 2 weeks ago are included.
Hella 007794301 weatherproof 20/40 AMP SPDT mini-relay. $9.18
Hella H84709001 Iso weatherproof relay connector with 12" leads. $12.45
Blue Sea Systems waterproof in-line ATO/ATC fuse holder. $8.79
I also bought 12 gage wire and shrink fit connectors.
Before I did it the right way I bought, again through Amazon and actually from Rare Electrical a 12 volt 15 tooth Model 18219N starter. $123.52.
Now I have an old Hitachi starter, that worked great, when it got electricity.
Once again, thanks.
