Any idea what this is?

It lives under the drivers seat of my 89 GT. Definitely stock Ford part but I haven't bothered to trace the wiring yet.

Thanks for any help.

Fuel Pump relay

It's the fuel pump relay.

Ditto. I've pulled mine so it hangs out the front of my seat and I've bent the retaining clip back a bit. That way I can pull it as a cheap kill switch when I park it someplace I don't trust 100%.

Thanks for identifying it.

I just wonder why it's under the seat? It seems like an odd location.
