Just FYI, this is only true on some Honda's/Acuras. If I remember correctly, the last vehicles to use an S type regulator were Integra GSR's and Legends. The green/white wire is normally the C wire on Honda's, NOT the S wire. The C wire is what the PCM sends a ground signal to the alternator to shut it off in economy mode. Gound the C terminal on a Honda, alt goes off like a lightswitch just like it's supposed to. You want better voltage on Honda's, just CUT the C wire and just stop the PCM from shutting the alt off.. If you try to put an inline diode on a C wire to B+ on ANY Honda, you WILL blow the regulator up. Just FYI, to my knowledge, from ~2002 there wasn't a single mainstream Honda/Acura made that had a sensing type regulator, and the last one I can think of was the Acura legend in '01-'02. No Civic or Accord has used an S type regulator since the early '90s, the last Civic to use it was I think '89...
THIS IS WHAT I READ..ITS 90'S MODELS I BELIEVE YOU CAN DO THIS WITH. mine is a 93 Legend
