747 Pin C9 to 730 ECM question
Installing a TPI SD in a 1994 K2500 5sp truck with 16196396 ECM which appears similar to the 747.
Can't determine where Pin C9 on the 396/747 transfers to the 730 ecm.
C9 is the Crank Signal on both the 396 and 747
attached diagram for the 747
Thanks

The '7730 with $8D doesn't use the crank signal. Can tape it off at the ECM end of the harness. Then someday when the starter is down can disconnect the other end.
I wouldn't pull it from the harness as down the road it could be re-purposed.

Re: 747 Pin C9 to 730 ECM question
Was hoping to locate an extra wire to run separate 5v references to A4 (MAP) and A5 (TPS)(730 ecm) but just joined them at A4 as per the wiring sticky above.
Thanks again
