Shift Light on OEM Tach

[dzcab]

I was thinking to see if anyone knew if there was a shift light that could be added to our existing oem tach, like an autometer type shift light. I don't want to add a whole autometer type one with shift light as I already have the tach. I seen some out there that can hook up directly to your existing tach but I am not sure if it compatible.

I like the one with the Orange LED shift light, Stand Alone Mini Digital Shift Light.
