Is there a way to id an aftermarket wiring harness as to which company produced it? My '75 Ranger has such a harness. After an engine rebuild there's a purple wire marked TFI start that was connected to the battery. I don't think that's correct. I'd think it should be in the start circuit. If there's a way to id the harness a schematic would also be nice.
After thinking and looking at this for a moment I believe this harness is for the efi/computer only. The oem fuse block is still there. My main concern is the TFI start wire.
