98 Yukon ECM fuse blew

So the oil pressure switch has a wire that runs as a back up to the fuel pump relay. Goes kinda like this:​

______ Fuel Pump Relay_______

Fuse<______Oil pressure Switch_____>-------back to tank (with the fuel level Sending unit wiring)--- ---->connector at tank<---Fuel Pump​

In the preview I could line the fuel Pump relay over the oil pressure switch but it won't post that way.
