[SML] Quiet solenoid?

[Joe]

Regarding those 5 wires.  Those were on the first few I happened to find on E-bay.  But, after looking again and sorting by price, I see that about half are 5-wire and the other half with 2 wires, or 2 connection spades. So, for the 2-wire, you just apply 12v to extend, and then reverse polarity to retract.
By the way, the search terms I used were "Car Lock Actuator"

  5 wires would generally be a stepping motor, but I haven't taken a car door apart recently.

 Car lock actuators are available for well under $10. They use a motor, rather than a solenoid, so don't go bang.  I've not used one.  Some have 5 wires. But I have no idea what each does
