wiring a inertia switch

Im putting a electric fuel pump in my car (69) and bought an inertia switch that will kick off in case of impact, Its a Ford product # pbt-gf15, it has 3 plugs marked NO,C,and NC.
I called mustang plus where I bought it and they cant tell me what goes to what no instuction or anything.
Thanks in advance

You could check continuity through the switch and the shake the swith to cause it to open and recheck. Should be able to narrow it down. I have the same switch laying around here somewhere that needs to be installed.

Without having one right in my hand, I know they only use 2 wires to it. (in/out). You should have gotten the factory plugin with it, then it'd be just plug it in and go......... (would think AnY junkyard would give that kinda stuff away).
That's where I"d go. Take your sidecutters, find a newer vehicle, (newer than 85 or so), and snip/snip...........

C is Common

NO is Normally Open

NC is Normally Closed

12v goes to Common

If the switch is not tripped due to impact ( NORMAL ) then the voltage will go through the switch and appear at the Normally Closed contact. This is where you wire to the pump ( You should actually use a relay as the inertia switch is probably not designed for high current long term use)

If the switch is tripped then the NC goes open killing the power. The Normally Open contact closes. This is a newer switch so it is equipped with the NO switch to light a bulb in the dash to alert you the inertia switch has been tripped. Older Fords don't have this feature and are thus a two contact NC switch. Stu

Thanks guys, I got the old multimeter out and came up with what stu said, Going to go ahead and hook light to the NO side.

Stu I plan on putting a re-lay ahead of a toggle switch( for an anti-thief device) Than to inertia switch, to pump. Will that pretty well protect inertia and pump?

Thanks again all
