I want to put a gauge pod on my windshield post. I think I need to remove the trim piece, mount the pod to it then run the wire down under the dash. correct me if I am wrong. How does that trim come off. Do I just pull it off? Do I start at the top or bottom? Push in someware? Has anyone done this and can tell me how? After I get it off, is there a gap or hole there to run the wire under the dash, or do I need to dill one? Any help would be apprecatited.
