What kind of MegaSquirt ECU do you have? MS1? MS2? The schematic you posted only applies to a particular kind of shift light for use with MS1. For MS2, you want to build a programmable output circuit. Be sure to use about a 330 ohm resistor inline with the LED:

(The diode isn't necessary if you're only driving an LED)

Yep, that's correct. ;-)
