Default RPM signal wire to ECU

i got the ECU wiring diagrams off of ravensblade for my 93 to install my SAFC. on the diagrams though, there is no input or output wire for RPM, but there is throttle of course. anyone have any other ECU printouts that could help me? thanks!

Engine speed is measured in Rotations Per Minute...

according to that link, the RPM wire is classified as the engine speed wire. also, the signal voltage is the same (0-13, or more) and its both noted as waveform. looks like a winner to me, someone catch everything there that i did?
