Hello,
Can anyone please tell me if there are any good usable 5V sources I can tap into in the 190E? I would like to install a wired dashcam, and possibly add a hidden USB port.
My car will actually be converted to diesel, so that should open up some more potential sources, since I am still keeping the gasoline ECU for RPM signal and such. I believe the TPS is powered by a 5V source, but I am not certain if it is constant or variable depending on the throttle signal.
The ECU pin for the TPS voltage supply is number 18, it seems.

If you gentlemen have any other recommendations, I would be glad to hear them.
Thank you.
