Hi, fellas i am new here and have a question about the coding plug in the cluster. Is she makes the problem in which i dont get speed signal to my cluster and dont catch econometer signal, too ? I connected my cables from the both looms ( c101 to x20 ) correctly as it is shown in many diagrams ;) So i dont think the problem should be in the wiring.
i am still trying to figuer out what caused this problem, and wont hide that i need help
P.S thanks in advance ...

i found that the problem is in the connection.... the cable from the ECU and the cluster was broken ...

Would the speed signal not still come from the original speed sensor in the diff? I have this exact problem. I have the revs showing but no speedo and the econometer is either on or off if u no what I mean.

There's a confusing of speed signals here! The speed signal Will is referring to is the engine speed signal (=RPM), which goes from the engine ECU to the instrument cluster.M1ke30 wrote:Would the speed signal not still come from the original speed sensor in the diff?

The road speed signal goes from the diff. to the instrument cluster, where it drives the speedo, odometer and econometer, and then is fed from the cluster to the engine ECU.
No speedo is normally an internally broken wire in the lead from the diff. sensor to the body, a dry solder joint on the speedo. circuit board, or, with other symptoms, a blown fuse.
The engine loom, and any problems with it, won't affect the speedo.
