Confirmation: DB37 pin/ harness wire orientation (spark issues) -MS1e/1997
I'm wiring a MS1e to a 1997 Miata as a standalone unit. Input/output mods for stock ignition have been done already, and confirmed.
I followed the two known diagrams for wiring a DB37 to a 1997 1.8, as a standalone setup:

MY CONFUSION/QUESTIONS/CONFIRMATION:
1. PIN26= 5VREF(3I) ?
2. PIN24= thick gray CAS(4F)... Does tach (b/w 4L) also go to PIN24 for an RPM signal from CKP?
*I'm trying to eliminate variables to track down why I'm not getting spark, or an RPM signal in Megatune. I assume no appropriate signals from the CAS to MS. (car runs perfectly with stock ECU wired)
*I do get the common MS "powered up spark jolt/firing" randomly, so I assume my ignitors are wired correctly and receiving signal?
