Hi there. I recently had a tachometer installed in my 1999 EK civ. Every thing was workin great up until last week. It seems when ever i need my night time lights on , i will go to to turn them on and my windshield wipers come on even though they are really off. Im wondering if the guy who put in my tach may have shorted out a circuit or possiblt taped into the wrong wires. Sometimes the whole left side lights of my car will freeze up( front day time lights/side markers/ and rears will stay illuminated. This has become very dangerous as to i cant make left hand signals :S . Now if i just put my day time runnin lights on , everything is fine, but as soon as i put my full lights on, my whipers go off and things get worse from there. I would really appreciate any feed back or suggestions. Thanks (IMG:style_emoticons/default/biggrin.gif)
