Where to get the little plugs for alarm sensors???

[TERRA Operative]

I've got a few sensors (microwave, tilt, etc) for car alarms that I've amassed over the years and I want to put them to use.

Problem is I need some of the 3 pin and 4 pin plugs, but they don't seem to be sold separately, or my Google-fu is a bit weak in that regard...
Does anyone know where to get them, or know what they are called etc? I need 3 pin and 4 pin versions, either as parts to crimp myself or with preterminated flyleads as supplied when you buy the sensors.

ashdown ingram or possibly jaycar for auto electrical supplies.
I'lld try jaycar first as probably cheaper but if they dont have what you need ashdown ingram should
goodluck

Cheers,
