Source for wiring harness pins
 

Does any body know of a source for the metal pins that are used in aftermarket harness adapters? Most of these adapters are sold by a company called Matra.

e.g., http://www.mobilcaraudio.com/page/page/912799.htm

Wires from the back of an aftermarket head unit can be attached to these adapters which are then plugged in to the stock factory harness so no factory wires need to be cut.

You still end up with a mess of crimps between the head unit wires and the adapter, however. I would like to avoid this by terminating the headunit wires with the metal pins that plug into the adapter.

I have discovered that the pins slide in and out of the adapter pretty easily, but are not reusable because they are crimped. I would like to find a source of uncrimped pins to use.
