Better off going to a junkyard and cutting a plug off with about 3 inches of wire on it, then splicing into your exisitng wire. That's your easiest route.
Mostly civic's and integras have these plugs. They are usually 2 wire plugs, but there are the one wire plug as well like you needed, just not as many. I have a 2 wire plug with about 4 inches of wire on it. Not sure if it will work, but it's the same exact plug, just 2 wires coming out of it instead of one. LMK if interested!
