I know there are two wires that go to the speed sensor. One is yellow and blue however, I can't seem to figure out what the other wire is. I know it is in the lower harness. I searched for a while and someone said something about a yellow and black wire but I haven't seen one.Does anyone know for sure what color wires go to the speed sensor plug?Thanks in advance :D

There's a yellow/black wire that is for the oil pressure sensor... And that goes all the way up where the oil filter is (the sensor is located 1-2 inches or so above it)BTW you're picture in your signature is friggin' sweet

Yeah, because I didn't do that already.

To clear things up:I redid all of my wiring, and when I redid the lower harness I used the ka fsm to find where the transmission plugs originally were. So I cut them off and wired them accordingly to the sr sensor plugs. Obviously though, somewhere between cutting the plugs and wiring them up I got the speed sensor wires somehow mixed up because I am getting no speed reading, nor am I seeing any kind of yellow and black wire that has been mentioned.I am not about to rip my lower harness apart to search for a wire that no one has given me any proof of whether or not it is actually there OR if it's even the right wire.
