What about a Crash Relay for Electric Fuel Pump

Do you have a pic of the connector?

Mine has three pins also but only two wires.

Thanks Bill, that looks like the connector I need. Why in the hell do they use custom connectors there? Any part numbers on it?

This has been a very informative thread to follow. Timely for me as I continue with my LS1 Nomad build.

Nobody chimed in on your question: “I was wondering what one of these things would do with a jolt from a hard shift”

Obviously, including this sensor switch makes all the sense in the world...in a collision where the fuel line has been breached, but the 12volt power has NOT shut down. Fires get going real fast with an open fuel line spewing fuel out...

But I too wondered how sensitive to movement this sensor would be. What a giant PITA to have to reset this thing all the time when shifting hard, driving hard, launching, etc.

Guess the only way to know is to install it and then find out later on. Could always remove it from the system, but that doesn’t do anything for ones sense of preserving their car from a total fire after an accident...

Paul, I don't know if there's any specs on the acceleration that would cause one of these things to trigger, or if there's different kinds of them. It seems like mine triggers fairly easily when hitting my hand with it. However, that is probably a very high acceleration event like a hard collision. My gut tells me that a hard shift isn't going to trigger one of these (I was just kinda thinking out loud). Even if it does, it's easy to disable it by bypassing it if it becomes a problem. I'm installing mine, and we'll see what happens. I think it's a good, inexpensive safety device that we hope we never need.
