I am adding the MSD 8918 rpm sensor and would like to verify the wiring.
I have the SparkFun Breakout and in the Wiki it has a note concerning boxes with either V+ or 5+terminals. (see 2nd attachment)
My box has the V+ terminals. (see 1st attachment)
I take it I need to run a wire from the SparkFun to an unused 5+ terminal (I am only using one load cell, so can use the 2nd load cell 5v)

Yes, do not use the V+ to power the SparkFun Breakout board. V+ is about 6.5 volt and you need 5V. Take from LoadCell2 for example.
Thank you Sir !!
I just added this same setup. I can get the RPM2 gauge to read the signal correctly, but I can not get the "ENGINE RPM" to register this signal on the gauge. Under RPM setup, I have the RPM2 input function set to ENGINE RPM, but I'm not getting anything. Am I doing something wrong?
