isn't a computer wired for 5v not 12v if you touch it with 12v wont you damage the ecu

@Howardtripper For this circuit, no, it is a 12v on/off square wave signal. For other lower voltage sensing circuits you still will not damage the computer with a higher voltage through your test light. The only voltage I have seen "hurt" an input circuit was an injector control wire touching a 5v ref. wire. This was causing 120volt spikes to surge through the entire 5v reference circuit. It cooked the MAP, AC pressure sensor and the PCM.

A cheep test light and a scan tool that provides OEM data is all you need. The scanner in the video is a Snap-on Solus Pro.
