Hitachi alternator plug/connector

I'm in the process of trying to fit a higher amp Nippondenso alternator into my old Trooper that originally came with a Hitachi unit. Pretty much figured out physical mounting and belt alignment issues but need to wire it.

I'd like to make an adapter instead of cutting up my stock harness if possible. I can't seem to find a connector that mimics the stock voltage regulator side.

My stock connector is like this:

stock voltage reg side:

^^^need a plug that looks just like that^^^

I contacted 3 vendors that sell the female terminal connector but still waiting on responses.

Anyone in the know of such a plug?

Just use individual crimp on spade terminals, use marine(the black stuff with the sealant) heat shrink tube over them or get the good ones that have a sealant lined heat shrink jacket on them.

This is how I adapted a Ford TPS to a Mazda wiring harness when I wanted to be able to undo the process. That was over 40k miles ago.

The wires aren't even secured to anything, they just flap in the breeze and beat against the water pump housing, never a connectivity issue.

This is how I installed a upgraded alternator we couldn't find a harness for(I believe it was a Hitachi for an old Datsun pickup), on a Yanamr one cylinder marine diesel(vibration machine). Used the insulated female terminals. Holding together fine.

I was hoping to make something nice and clean similar to this:

but evidently the Hitachi plug I needed does not exist.

so I got a new ND connector & pigtail with crimp/heat shrink terminals and some rubber cap thing I had laying around and came up with this:

to mate to this:

nothing melted or caught on fire so I matched the wires correctly and now I have 80a instead of the stock 50a.

more importantly I have eliminated the problematic voltage regulator used in the stock alts that never last very long. note how clean and new the alt on the right looks, it was already crapping out while the 26 year old filthy ND from my 2.0L Impulse has been sitting unused for almost a decade and still works fine.
