guys..i've installed indiglo gauges at my previous cars and all of them failed after some time...my question is..for the wire where you have to connect to get power...how do you do that...i know taht you're supposed to tap into the black wire with red strip..or red wire w/ black sripes (not sure) but how do you guys tap it? any ideas? i tried just forcing the wire into the socket but it came off after a while..and i tried using a wire-tap from radioshack but it didn't work....not sure if it's the wrong size or the wrong equipment...can you guys give me some ideas?
