Bought a Meziere to install my on my new 09 Silverado. I want to trigger my electric water pump relay off of the fuel pump relay, but I looked for the fuel pump relay at the under hood fuse panel the fuel pump relay socket is EMPTY. The socket is there and it is labeled Fuel Pump Relay, but there is NO RELAY. Does anyone know what is up with this. There has to be a relay somewhere. The current is too high for the ECM to trigger the pump directly. I'm baffled by this. Is there another circuit I can trigger off of? I've checked Helm, Alldata and Mitchell, but they don't have manuals ready for the 09s yet

The fuel pump is controlled by a separate module that is mounted near the spare tire under the bed so that is why there is no relay in the fuse panel.
