2.3 EFI conversion for track car.

[brianstrange]

Hello, and thank you all for supporting this hobby.

I'm currently building a 2.3 Fox Mustang race car, and I'm wiring up a stock 2.3 EFI, with plans of modifying, or going Turbo at a later date. I've done over 10 V8 EFI Conversions, and the wiring is no issue. I'm hoping to better understand a couple of circuits on the 2.3 EC (EEC IV) so I can wire them up properly. 

87 4 spark plug motor, 87 ECU

Does anyone know how the following circuits function (Meaning what they actually do?)

Pin 2 Brake on - off

Pin 24 Power Steering Pressure

Also, I read that connecting the AC Clutch circuit to pin 46 creates a timing change that works well with premium fuels.  Is this true?

If you know of any sneaky tune tricks in respect to the wiring or setup, I'd love to hear them.    Again, no turbo for now.  I'm running a stripped car, with mostly weight reduction mods.  We plan or running it at Lemons \ Chump events.

Pin 2 just goes to the switch on the brake, says if it is pressed or not.

Pin 24 gives it extra air via the IAC valve when power steering pressure goes up to prevent stalling at low RPM when steering effort is high.

Pin 46 is the signal return (ground) so I have no idea how connecting it to the AC Clutch circuit would do anything positive, particularly when that 87 Mustang ECU doesn't even have a "premium" fuel table.
