88 ECM pinout question.

Is there a better (clearer) ECM pin out sheet that the one over at diy-efi.org/pub/gmecm/manuals/? It's really grainy, and it doesn't print well.
I want one to put on a disk, and to print to take to the car. My car is 3 hours away in storage. I have to take everything with me when I go.

Thanks for any help!!

88 IROC 5.7 with the 165 ECM

Here is the original link I messed up the first time: ftp://ftp.diy-efi.org/pub/gmecm/manuals/1227165/

I have to repin the ECM connector after I get it through the firewall, and I have to add/ remove a few wires too. I really apprichate it!
