What does pin 13 connect to?

Well I am almost 100% sure that my ecu is causing my car to die after a couple seconds because I tested the MPI relay and it's fine, the MPI fuse is good, and when I ground pin 56 on the ECU the fuel pump stays running. I am currently trying to contact wiseman Steve to buy an ECU from him but I haven't heard back from him in a week. The last thing I want to try to do is put a new wire in on pin 13 of the ECU and see if that fixes it but I can't figure out what pin 13 connects to. I looked at the wiring diagram and it said pin 13 goes to the control relay but I don't know what that is or where it is and I can't find anything about it in my Chiltons and Haynes manuals. Is it the MPI relay? If so which pin on the relay?

Pin 13 on a 1g is for "fuel pump voltage monitor input"

I know that on vfaq it says that it connects to the Control Relay. What I want to know is where that is and what pin it connects to on the Control Relay so I an run a new wire between that pin and pin 13 of the ECU to see if my ECU does have a problem or if there is just a break in the wire somewhere

Pin 13 is the fuel pump (FP) control sense line. It actually goes to pin 2 of the MPI/FP control relay (which runs the FP) as well as to the FP itself and the FP test connector. The sense line lets the ECU know that the MPI/FP relay turned on to provide power to the FP.
