Throttle Possition ECU wire for RB20DET

Hi all, well I bought an HKS EIDS for my 90' R32 Skyline GTS-t RB20DET. I don't know what wire on the ECU to hook it up to. I have everything hooked up right but the throttle possition sensor wire (most important). The RB20DET Manual Trans. doesn't have the wire pinout #56 "Throttle sensor output signal" on the ECU, only the automatics have this wire!! So I need to know which wire to hook it up too??? Any one have an open air BOV set up and have an Idle control system, that can help me???? My car keeps dying from the MAP sensor readings at idle and stop.

Please HElp ASAP!!!!!!!!

Thanks,
ERic
