Brief Description: Wire Oil/Fuel Pressure and Oil Temp Senders
I'm really starting to get into the wiring. It's much easier than I originally thought. The toughest part is figuring out how to run and support the wires.
After connecting up the power/grounds for both Dynon units I decided to start focusing on the EMS wiring. The EMS harness for the various sensors is made up of a ton of uniquely colored wires while the harness for the EGT and CHT probes are all brown but each carry a label that is heat shrinked indicating which cylinder they all go to.
I started working on the colored wires first by wiring up the oil and fuel pressure transducers. The oil pressure transducer gets the yellow/white wire with no ground since the case itself is grounded while the fuel pressure transducer is hooked up with the brown wire and the ground from pin 5.
The oil temperature sender is also grounded via the engine ground and connects to the EMS via the brown/white wire.
The EMS had two sets of red/black/yellow wires. The twisted group are for the fuel flow sender while the stand-alone versions are for the power, keep-alive power, and ground-in.
