I have a green wire on the Howell fuel injection harness that has a green wire which reads "A/C Request". I would like to buy a vowel as to where this wire goes?
Thanks Guys,
Tom K.

taped up and not used. Probably the best answer.
it would go to the A/C high pressure switch. I believe it senses voltage there when the A/C clutch gets power to engage, and it kicks the idle up a little to cover the compressor load on engine.. I don't think many people hook up that wire. I have a sandeen compressor, so I can't even tell any change in rpm when my compressor kicks in, so it is not hooked up on my efi(ebl/rochester- not a howell, but almost identical wiring wise).
