The tach wants the "W" terminal on the alternator. Do any of those have a W terminal?
Otherwise, you could add the W terminal with a little surgery:
Gas Tacho / Revcounter Conversion to Diesel W terminal
And there are YT videos showing how.
I ended up having my bad alternator rebuilt at a local starter/alternator (in-house) rebuild shop. PIA to deal with the know-it-all grumpy guy but he did a good job.
