Isuzu 2.6l alternator wiring

I didn't see a better place to put this thread so.... I've got a '93 spacecab that the guy before me installed a Chevy high output alternator on. He did a real clean job by soldering in the plug to fit the new alternator. The problem is, I'm reinstalling the stock alternator so I need to revert back to the stock plug. Does anyone on here know of a company that makes an adapter plug to go from Chevy to Isuzu?

Figure it out yet?
