Might be a oddly specific question but I had purchased a JDM 180 kmph speedometer awhile back and tried to swap it into the original USDM cluster but it didn't work. I thought I might have screwed something up with the cluster so swapped the original back in and everything is functional again. The range is quite different as the JDM speedometer has the km markings similarly to the mph marking on the original. I would have thought maybe calibration would be an issue but the JDM one didn't register anything at any speed. Anyone run into similar problems or have successfully done the swap that could shed some light? Do I have a defective JDM speedometer maybe?
