The other end of the lt green wire goes to the AFM connector. So, you could wire pin 27 to 2O, which will come out to the AFM connector, then just jump the two there with a smal peice of wire...this assumes the AFM has been removed, otherwise, the AFM itself takes care of the pump.
if you run it straight to the lt. green wire, just splice it in.

here:
Depending on your harness, you'd want:
Pin 4 or 2* to go to the black/grn wire - this is a ground. * Not sure which you need to use.
Pin 1 to go to your R wire - this goes back to 1N on the ECU harness and should connect to 5vref from the MS.
Pin 5 to go to your LG/WHt wire - this goes back to 2L on your ECU harness and should connect to the TPS input to the MS.
You will need to source a linear TPS from the aftermarket or from another application. The easiest swap is probably a BMW TPS Bosch part # 0-280-120-402 from an auto E30 or E36, or Bosch #0-280-120-406 from an E32. Both of these should bolt on your miata TB w/o modification. You will need to adapt the wiring harness to accomodate.
The BMW pinout is:
Pin 1-black wire-5volt in
Pin 2-shielded wire-ground
Pin 3-yellow wire-signal out
Pin 4-ground
Pin 5-WOT switch
Pin 6-Closed switch

if the stock computer runs anything on the engine, then yes you would? If its just running idle, I doubt you would need a narrowband. Idle might be a bit rich, but shouldn't be anything crazy.
stock ecu will run the car without a narrowband, it just gets shitty gas mileage and runs a bit less smooth.

why do you have a stock computer still if you're talking about megasquirt?
