Speed sensor wiring all messed up??
 

Hello, I have a 2000 honda accord DX with the manual transmission. Anyways, I am pretty sure the speed sensor itself works. The gasket is all good, and the little gear on it spins easily and without noise. The problem I have with it is the wiring to the plug. There is 3 wires, they seem to not want to "click" in to their designated plug holes, and I can very easily pull them out when I jam them in there. I am pretty sure I have the wires in their correct holes, because the speedometer does jump every once in a while. Any ideas on why my speedometer doesn't work would be great!
