hi i want to change out my gauges on my boat, fuel,trim, and tach. they work i just don't like the black, id like to get them on here and i know what i want. question is do you just undo the wire from under the console and replace or is there a whole can of stuff im opening up just so i think it will look good? Thank you. <br /><br />1995 cobia CC 174 1995 yamaha 85hp.
