Also, do "NOT" do this with the ignition on !!!!!!!
The round part in the middle of the ECU is called the Switching Transistor. Touch it with the ignition on and you will be getting a very LARGE JOLT !!!!!!!!
Oh that picture was taken with the car running... the next time I tried to touch it I felt the electric pulses but not a big jolt, I pulled my hand away pretty quick though. I guess you can say I'm faster than electricity lol jk.
The only place I've been shocked from is that damn coil, if the car is running and I get to close to it I get shocked.
