Disco 2 alternator adaptor wiring question

hi all. seems I put this question in the wrong place yesterday, so I'll try again. I've replaced the alternator on
my disco 2 TD5 and new adaptor ( couldn't find a genuine 2-wire to 3 pin female adaptor ) has 3 wires,
black, red, black. could someone tell me whether I ignore the third wire or how to connect all three to existing
wiring. many thanks, steve

What brand and part number is your alt?

Hi Juke. Original Denso alt. DAN 670 021080-0290. thanks. steve

Hi, what's that "adaptor" ? if you mean the electric connector on it's back you must connect the brown/yellow wire to pin 1 and white/green to pin 2, pin 3 is unconnected

Hi. The adaptor is meant to replace the original connector which had brown/yellow and white/green wires into the connector which then plugged
into the back of the alternator; unfortunately, the original one fried and the only way to attach the new one is using the adaptor. So, from the back of the unit
there is a female 3-pin plug into which the adaptor is connected; at the back there are 3 wires, black from terminal 1, red from 2 and black from 3. How do I
wire the new 3 wires to existing B/Y and W/G wires? I'm living in a remote part of Australia and don,t have access to Landy wreckers or original parts, so
I often have to adapt what,s available. If someone has an original connector that they want to sell, please let me know. steve

Should be obvious from my first reply how to connect the wires, the WG as to reach pin 2(middle) on the alternator's plug and the NY to pin 1

Hi, thanks for your reply; yes, it is obvious where the N/Y and W/G are connected and it would be easy if the connector was fitted with the matching wires instead of 3 different ones. Sorry if I've wasted
your time. Steve

As mentioned by SF, only 2 pins are needed for a genuine alternator. I would just insulate the pin 3 wire just in case you will need at a later stage - some aftermarket regulators use this pin to monitor the output, in which case it would be connected to alternator battery feed.

Hi. Many thanks for your reply.
regards. Steve
