small clarification. SO I can put the resistor inline with the signal wire going to MS. and when building the board just skip where is says for the vr/ hall sensor?
No, you need to build the Hall/opto circuit and configure it using the 330 ohm - 1.5k ohm resistor as shown in the schematic you posted. We use the standard 390 ohm resistor (R12) in our ECU's, but connect a 1k ohm resistor in series between the R12 and 5V/Vcc.
