So I'll have the pusher/big line kit from Vulcan soon and I want to switch the LP power source from the ECM to a direct 12v supply. I figure I should also add the 'interrupt' relay to stop the LP when the engine is cranking. How does the attached diagram look? Any problems?* Sorry in advance for the crappy drawing.

When I had my AirDog installed... I cut the leads off the OEM lift pump to plug into the truck harness for the relay trigger. Soldered & liquid tape to seal the connection. The main power for the new lift pump relay is off a hot lead from the battery. Best of both worlds.

Not a bad idea... Good design...
