I'm trying to change the vehicle speed sensor on a 91 corolla. The odometer and the speedometer does not work and i figured that it is the vss. I actually went to the junkyard and got some parts but took everything that actually connects to the transmission. The only 2 parts is the pictures below. Can someone tell me what these parts are and what they do?!?!?!? I changed the triangle part in my car but that did not solve anything. Thanks for the help.
