Installing a Meziere electric water pump on my 09 Silverado. Using a 40A relay to provide 12Vdc to the pump. Want to trigger the relay off of the fuel pump relay. Looked under the hood at the FUSE/RELAY panel. Found the location for the relay, but the relay socket is EMPTY. What's up with that? No relay for the fuel pump? I know the ECM can provide enough current to power a fuel pump so where the heck did they move the relay to?
