Looks like the PCM drives the FP relay coil on connector 4 pin 36 to RCM connector E pin 3 to me.
When energized the FP relay supplies 12v via the RCM fuse 5 to the pump.
What I don't get is that dotted line ground from G204 to connector B pin 5 on the RCM.
If that were truly connected, ain't no way fuse 5 would last more than 1 ms.

Any idea what that dotted line signifies ?
