MegaSquirt 3.0 with PNP ("Boomslang") harness
I've got a Megasquirt v3 with all the Miata mods done to it, and a harness made out of spare ECU connectors so there's no cutting or splicing necessary except for the fuel pump wire, obviously.
Sorry for the crappy cell phone pic.
$425 shipped.

The stock fuel pump wiring doesn't interact with the ECU, it uses the AFM. Once idle air is holding the flapper door open ever so slightly, the fuel pump is on. Since you get rid of the AFM with a MS install, you need to give the MS control of the FP by running a wire from the MS to the FP relay under the dash.
A how-to is documented in the useful MS threads section.
