iv got a 1995 mustang gt iv done a carb conversion on it with a HEI distributor. i wana use the factory wiring and don't want to hook the fuel pump up to a switch to run all out all the time. theirs a signal wire that goes to the distributor or the TFI to tell the pump how much to pump depending on the RPM i cant find it. theirs a six wire pigtail that went to go to the old distributor i think it might be one of them.
