1973 914 current flow diagram

Throwing this one out to the brain trust here. Anybody know where I might find a current flow diagram for my '73 914 2.0 (I believe Porsche produced one in the '70's)? All of the "pin to pin" connections on my relay board indicate continuity but I still don't have continuity through the black/red wire from pin 13 to the fuel pump. the power supply and fuel pump relays are new and test perfectly. I have replaced the 14 pin connector and thoroughly cleaned the board and connectors as well. I just want to know if I am missing something before I run a new wire to replace the black/red one.

TIA
