dude man seems like you're askin' for it. You're just bombarding people with silly little question after silly little question. If you can't operate some simple little hand tools like maybe a screwdriver then it makes me wonder if you know where your key goes to start your car. To answer your question about getting to your gauge cluster...you better watch out man, there's a factory installed shocker to prevent people from screwing around with the odometer...pumps out like 10 000 Volts, watch your fingers!!! Just givin' ya a heads up!
