Lift Pump Oil Pressure Switch Cutoff

[niteflite1287]

I'm installing an AirDog II into my truck (LB7) soon and would like to install a low oil pressure cutoff switch into the circuit to kill the pump if the engine is off but the truck is left in run or during if i managed to get myself into an accident. I have had a hard time finding a a switch. Summit makes one, but it has blade terminals and I was hoping for a metri-pak or equivalent connector based setup. Anyone know where I can find one of those. Also maybe I haven't looked hard enough but does anyone know the sizes of the spare plugged fittings on the oil filter house. I have read there are three is this right?

If its for the 02 in your sig, the simplest option is to get an oil pressure sending unit and plug for a 94-99 6.5 powered truck. They have an oil pressure switch built in and use the same resitance as your stock sender in your 02. One wire will be for the guage, and the other 2 you can use to trigger a relay for your lift pump. Or you can go with the KENNEDY switch set-up he sells for the 6.5's. It will shut the lift pump off if no oil pressure is present, but it also has a prime function to actuate the lift pump for a few seconds before start-up.
