I just bought a CSR electric water pump for a sbc. I just wanted to see what guys are doing to run them.. Should I be using some kind of relay and power it seperate with a swtch, or can i wire it in somewhere in the fuse box to power on when the key is on? Any help would be great Thanks.

 

relay and a on/off switch for it. The water pump should have wiring suggestions in directions

 

I just received a proform electric pump today, and it had no instructions. I am going to wire it into a 30amp relay and tie it into my holley hp efi ecu for power once ignition is on, along with my dual fans on the radiator.

 

Thanks for the replys.. Not to get off subject but how is that new HP ecu?

 

I love the thing, I can hop into my car, fire it up and drive off like stock. Except I am far from stock. HP EFI has so many little tricks you can wire it up for as well. I think there is a total of four i/o's you can use for whatever. I use one for a shift light, one for fan/waterpump on off. It is configured to be on with ignition, off for cranking, then back on once engine is running.
I am saving another i/o wire for the meth injection.
