no fuel pump operation after lb9 engine harness swap

the fuel pump checks out okay, the green wire from ecm is putting out a signal, I have 12 volts at orange power wire, good ground. Wondering if thec207 connector or c100 connector has fuel pump wiring, all suggestions of c100 views show no fuel pump wiring, If anyone knows where the tan/white(gray) fuel pump fed wire is routed throughout body, please let me know as Im using only the computer and engine harness wiring from a v8. If i jump a wire from the fuel pumps tan/white(gray) at pump connector, to white tan (greay at relay, i get a constant fuel pump power with KOEO, pump will constantly run, any help is appreciated

The gray wire from the relay goes thru C100.


Happy Racing!
