I tried these pin-type connectors and found they easily pulled out of the brass connectors after you get them in. I have a custom dash with aftermarket gauges and could not bring myself to cut the new under-dash wiring harness. So I removed the plastic piece, put them together one at a time and heat shrinked them to keep them from falling apart. Looking at 4spdragtop post it looks like he is looking for the other side of the pin connectors? That might work. Just wanted to share my experience.
