Well I finally managed to find the correct EVIC for my Libby. On my way through Bible Hill yesterday I visited a salvage yard and discovered an 04 Liberty Limited with an intact EVIC. I was some pleased when I plugged it into my Libby's EVIC harness and the temperature display popped up
You see I've already installed an EVIC in my Libby but it's from an 03 and won't display temperatures on an 04.
So on my way home yesterday I was able to easily watch the exterior temperature rise & fall as I drove through the Cobequid Bypass. Quite a difference in temps, maybe I'll be able to predict Black ice.
