1 Wire Alternator Options

Toyota 4Runner (1985 to 1991 with L4 engine)
The Toyota alternator that fits this application can be purchased as Bosch remanufactured part number AL218X.This number cross references over to Denso 210-0106 and 210-0107 as well as original Toyota number 27060-35060 and 27060-35061.

i used a Napa 213-8283
bracket. 60 amp Alternator Kit
you'll need the plug too.. Denso Pigtail Harness for Denso 210-0106 Alternators
That looks super easy. I may do this on my next build.

I bought a couple one-wire Chrysler case alternators from Summit years ago for like $99, now they are double in price.
But if they go out along-side the road, you are screwed.
