mass air pin question

I am building my own mass air harness and I am going off some instructions from an overlay harness and it says:

Move Smog Pump TAB Solenoid from computer pin 51 to pin 38
Move Smog Pump TAD Solenoid from computer pin 11 to pin 32
What do I do with pin 38 which is the EPC? What is the EPC? Is that the MAP? Does the mustang comp. use it? or do I just leave it off?

Never mind, I just answered my own question. Applies to E4OD only.

Yep, EPC = Electronic Position Control or what we refer to as the MLPS (Manual Lever Positioning Sensor) Pin 38 receives VREF signal changes from the MLPS in trucks so equipped.
