So this is my first post as I'm not quite understanding my problem and not sure how to better phrase it so google understands, I have an 08 GT limited 5eat and I replaced my standard clock with and earlier model one that had the mpg and other displays in it. Following multiple sources on the Internet, I've managed to wire the gauge up as best to the various diagrams I've seen, closest I've gotten was I managed to get err to appear on the display. I understand this is a problem communicating with the the cluster and the clock. I'm wondering if the 08-09 had a different communication wire than pin a18, anyone out there have performed such a feat and has any advice? Thanks in advance
