Looking for 1999 Vortec 454 ecu pinout

I am trying to find the ECU pin location of the cam and crank wires on a 1999 Silverado 454 Vortec engine. The single coil old style 454 not the newer one.

Thanks ahead of time.

Can you make the schematic a little bigger, It comes out pixelated when printed or zoomed in enough to read.

Thanks
