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:

I have ms1 v3. and I want to use a 12v light that I bought at radio shack I just noticed its not an led it says lamp, package didnt have any specifications on it.

Just connect the input of the circuit to JS2. Since the "lamp" you have could be an incandescent bulb, I'd recommend using the diode; in other words, build the circuit exactly like you see it in the link.
