1227747 VSS wiring question

[EDZIP]

Getting ready to put together a stand alone (streetrod) harness for a TBI with 700R4 using the 747 ECM. Pin A10 indicates it is for "Speed Sensor Signal" (dash cluster?) but I don't see any ECM pins for the (2) VSS wires from the 700R4 speed sensor.

Is a DRAC required? -or- How are the (2) VSS wires tied into the 747 ECM? IN A NUTSHELL...how is the VSS tied into the ECM?

Used to working with the 730 ECM which has (2) specific pins for the VSS (4 pulse).

Thanks

Ed
