Speedo doesn't work

[keefus16]

Let me fill you in.

S13 SR20DET in S14 chassis - Bought the car knowing the sensor didn't work - it had the s13 speed sensor on the manual tranny - changed it out with s14 manual speed sensor - still no go - checked the FSM and it says the wires to the sensor should be R/Y and R - The Speed Sending wire is Y with Green stripe from ECU to Speedo - I checked the wire colors to the sensor yesterday and they are YwBlack stripe and YwBlue stripe - Now I'm really confused - So, help me out. Does the sensor require a sending wire and power wire or not? I think the sensor itself grounds to the transmission with the bolt that holds it on. Let me know.

Just another note to this - I ran 2 wires from the sensor all the way to the back of cluster to the RwYellow stripe wire and to the R wire - which by the FSM that is where is connects to and same result - so, I was thinking it was the cluster - changed cluster out with same result - help me out guys

i think you might have fucked up on wiring the sensor to the cluster.. my speedo didn't work and it was because of the wires. i re did them twice, and on the second time it worked

did u check to see if the tcc box is blown???? its the lil whit box inside the kick panel on the drivers side. Unplug it and check to see if the circuit board is burnt inside.
