This is an ebay listing,
Wondered if anyone knows how to hook this up.. looks like the plug is different and there is an extra wire with a female round connector.

bidding says that it fits a 71-73 1200

You're right -- 1971-1973 1200 doesn't use one like that.

If you need a regulator, I recommend going to NAPA and get a 35A internally-regulated alternator for 1980 Datsun 720 pickup (not the 60A, but the 35A). It is a direct bolt-on for the stock 1200 alternator and has more reliable solid state regulator built in.

This new-type alternator is less expensive here ($50) than a voltage regulator by itself!

The one pictured on eBay is a New Era 522 unit.

The extra wire is a for IGN, which seems superflous since the rectangular connection already connection an IGN pin.

I suppose they made it this way so it fits a variety of cars including Datsun, Toyota and Hino.

thanks bro
got a wiring schematic for hooking up the NAPA one?

Nissan 23100-B9810 (Mitsubishi A1T22971/Hitachi LR135)

It is too simple for a wiring diagram. After you install the LR135 alternator, disconnect the old external regulator, and in the engine-harness connector, jump the White/red wire to the White/black wire.

I just purchased one of these

http://www.ebay.com.au/itm/Datsun-120 ... ories&hash=item5644287b5c

It has not arrived yet but looks to be exactly the same as i already have in the Car

Yes, that one will work. It is not original, but is probably IC (solid state) so better than original.

you da man DD
going to pick one up tomorrow

Just got to thinking, if you have a 1973 1200 with automatic-choke, then you need two wires.
