EEC-IV Schematics

Hey folks
I am trying to get my ECM repair'd. Circuit 47 burned out from the Fuel pump relay shorting out.

The place i asked if they could repair it, said they need a schematic for the ECM. Does anyone have them? http://www.auto-diagnostics.info/pdf/ford_eectec10.pdf
Looks pretty good. However it doesn't say its for a 4.9L
My ECM is E8TF-12A650-Y2B

There are a few reverse engineered schematics floating around. Any decent electronics shop should be able to do repair without a schematic.

Circuit 47?
How did you figure that out?

Here is the only EEC-IV schematic out there that is worth anything, its old, may or may not be same as what you have:

A good electronics person should be able to follow the PCB. That shop is just wanting a map to help guide them through the maze of the pcb which does help and speed things up a little when tracing out a circuit and troubleshooting.
