Ok so I finished my heatercore today..works good..everything is nice and tight and only like 3 extra screws..which were like screws for pratically nothing...well heres what i think i did but let me ask u guys before i check tomorrow..i think i plugged in one of the harnesses to the back of gauge cluster upside down..because everything on the left side , like the tach and temp..is acting really funny and then when i turn my lights on ..everything is spazing out and only half the cluster lights up..so did i simply plug it in the wrong way or is it something else
