Does anyone here know how to clear ECU Check Engine codes? I know how to check them (put the blue wire in slot #2 of the little black terminal), but can't figure out how to clear them.

Apparently, you're supposed to stick both of the blue wires into slot #1 and #2 in the little black terminal, then turn the key to "ON". I tried this, and it didn't work. I even tried starting the car, which didn't work.

What am I doing wrong?
