So finally installed everything. I discovered a extra ground pin on the connector that not populated on the pre 17 cars. So, adding the ground cable will be easier then what i was originally thinking. So its just a matter of adding three pins to the back of the Cluster connector.
Woh! it does make it feel a tad Better.
OH! random! Apparently the cluster stores not only if its KPM vs MPH, Ambient in C or F.... but the Automatic AC temp.. When i corrected the odometer Mileage on the eeprom for my car... i flipped a bit down bellow those setting. On the bench i did not see anything but as soon as i plugged it into the car the car... the AC switched to C lol...
