The EMS has one common power wire for the MAP sensor, oil & fuel pressure sensors. I had previously run the wire out to the MAP sensor and terminated the end. This left some slack so I cut the wire mid point of the run to connect the oil & fuel pressure sensors. I used a short piece of wire as a jumper between the two connections so that all sensors will have power. I used butt splices to make the connections to the sensors. Next, I used butt splices to connect the sensors to the “data” wires that run back to the EMS. I also terminated one of the wires to an oil pressure switch which will turn on a red light in the panel when oil pressure is below 15 psi. When the pressure is above that number, it runs the Hobbs meter. When the engine is off the red light also serves as a reminder that the master switch is still on—anyone ever left the master on to find a drained battery the next day? Yep, I thought so! Now I’m waiting on an order for more ring terminals, clamps and shielded wire for the P leads off of the mags.
