hi to all members.i put in my vw beetle an ej22 91 model .the donor car had manual trans.
my question is. should I ground this single wire from b58 pin 10.? or leave it free.? thanks.
should I fabricated a switch just to imitate the original neutral switch.?

Hi George, I think it is only a problem if your alternator is doing something its not supposed to do. What you said about that pin being a diagnostic pin from the manufacturer makes sense. I don't think they would support a 25 year old product, but did you contact the alternator manufacturer direct...

The 1991 and 1992 USDM service manual has different plug and pin numbers than your information. It is called plug f10, and every description lists only pins f10.2, f10.3, and f10.4. Pin 2=S, pin 3=L and pin 4= IG. There is no reference to pin 1 ("D" in the diagram I posted earlier). I did...

I don't have the service manual for the (unspecified country) Legacy you have. I have the 1991 USDM Legacy FSMs. I am running a japanese ej20g ecu in my USDM Legacy, the only wiring change i made was an ignition converter to allow the ecu to run wasted spark. You have mentioned the G2 ecu a couple ...

I'll look through the service manual after work and get back to you. Thanks and sorry if I was annoying.if can send me the wiring diagram for this JDM ECU G2 I would be very happy. I do have many diagrams and service manuals but nowhere shows that that D pin from alternator goes to the D21 Ecu.all ...

People on this board have been successfully running 2 wire alternators by only connecting the S and L wires to the new plug. Are you saying yours isn't working, or are you concerned about the IG and D pins not being used? I am concerned about the D pin.one last question.the D pin recieve signal fro...

George, you can tape up that wire and tuck it away. I don't know if you caught my edit, but remember that the wiring on the plug side is reversed compared to the diagram above. I believe the D wire connects to the ECU, which sends it a signal to turn on. The newer alternators turn on automatically ...

Good Morning George. The American 90-94 Legacys came with a round plug like yours. There are wiring differences between the JDM, EDM, AUDM, USDM etc Legacys, though I'm not sure this is one of them. The second post in this thread has links to the 90-94 Alternator and a newer alternator. http://www....

Hi. I want to upgrade the early legacy 1992 alternator with a newer 3 or 2 plug one.my alternator has the round plug with 4 wires Hitachi. I think the 4th one which is green with black stripe (D)goes to the ECU ???for some kind of Ecu control..I am not sure .does this wire leads to the Ecu ???I can ...

Yes, the newer subaru 2-pin alternators will work on your 92 Legacy. You will need to get the new plug and splice it into the appropriate wires on the stock alternator harness. Hi. I want to do the same thing.my alternator has the the round plug with 4 wires Hitachi. I think the 4th one which is gr...

i was wondering if the alternator s from a newer subie will work on my 92 legacy. something that will have a touch more amperage that the stock alt thanx for all your help with this Good morning. I want to do the same thing to my car .upgrade the early one with a newer.was your alt 3 plug wires or ...
