Hi all, For those of you who are waiting for the schematic, please hang in there. I am still working on it. I have discovered that there are a couple of diodes in the interior harness, and, I have been in contact with Floscan and they have given me electrical info for the Fuel Flow Sensor. I'll post it as soon as I can. By the way, I am creating the schematic in AutoCAD. I can post a JPEG file and the original AutoCAD file if people want. Let me know.
