Hello Im new here, but i recently did a aristo vvti swap on my gs300. I have original jdm harness loom and ecu. everything plugs in but mainly my problem im having is getting my speedometer to work. i believe its the cowl harness wire from engine to ecu, but i can not pinpoint which wire it its. im not sure if the wires are coming from the multiplex or etc.
Here is what is showing up on my gauge. My "vsc" and "vsc off" light is on and speedometer is not working.
