Wiring Bosch 420

Wiring Bosch 420
I'd like to wire this pump into the factory wiring. This way it can run under the factory relay, and that is less wiring for me. Does anyone see a problem with this? All I should have to do is run the switch 12 volt from the stock pump over to the Bosch 420 and ground the other side, correct? It seems easy enough, but it may seem to easy. FWIW, I plan to purchase the Racetronix harness to upgrade the factory wiring and it is still plug n play.

Thats what i did..... i was told that the 420L was to much pump and would burn out the stock relay..... so i added a bigger one..... so the stocker clicks on the new relay wich in turn powers on the pump..... Ill be running 2 Bousch 420L with my new setup.......
