i got this brown and yellow wire/connector that comes out of the middle slot of the dme box. One wire looks like it connects to a sensor and it also has a short ground wire that’s attached to it. I’ve looked all over the engine for a sensor I’m not sure where it goes. Any guidance or ideas are appreciated.
