1 wire internal or external oem alternator

denso stuff is nice ,need to make sure you have a large enough power and ground cables and connections
i think the biggest problem with any oe stuff is the builder ,if its remain most likey junk ,if new oe most likely junk
if you want good oe you need to find a rebuilder that uses good parts ,i have customers that i've put aftermarket starter in twice only to have to byu from the dealer
so not all parts are the same in the words of tommy boy the warrenty only gives the buyer a warm feeling ,not going to get you off the side of the road
