Ok guys, my speedo was working before with my old gsr motor. Now with the new ls vtec turbo swap. Everythin works on cluster except speedo. Speedo doesnt move at all. We try using another vss and still doesnt budge. What could be the problem guys?? It is annoying without speedo especially with the power im pushing

Is Vtec coming on right? If it is that means that the ecu is getting spead readings and that the problem is probly the guage cluister. IF Vtec isn't working then the ecu isn't getting a reading eather. First of all, any cels? Seconds, tripple check all ur grounds, make sure they're all nice and TIGHT. 3rd, check the connector going to the vss, make sure it's not dirty and filled up with dirt crap.
