Did that! As a matter of fact there is no rear seat so that was an easy check.Look under the carpet under the rear passenger seat.
Sorry it took so long to respond, I had forgotten about this thread til a friend of mine asked if I had a FPDM. The carpet doesn't go all the way back so ya, I looked there as well. I even tried tracing the wires back up from the gas tank but no luck with that either. I'm totally stumped on this!I should have said, it was under the carpet too, it's secured in with a bolt there. Maybe you didn't look under carpet?!?
