I was tryin to install my new tach and i hooked everything up but i put the green wire on a black wire that comes out of the ignition coil and goes into the distributer body. the tach came with these connectors where the green wire runs parallel to the tach wire and you clamp it and a little piece of metal pierces the black tach wire. so i did that and i go to start up the car and it makes this horrible sound like th starter is turning wierd. SO I UNclamp the black tach wire and the wire was kinda pierced and cut so i had to slpice it back together with some other wire and now its still sounds bad when the starter turns but it sounds like crap. so i unhook everything same result. then i turn on the radio and i was turning up the sound the dome light and radio face start pulsing like getting bright then dark then the speakers start doing it so no everythings pulsing. so i turn on the orange headlights and like no sound is coming out the dome light and radio light are pulsing. WTF DID I DO ??????? the car wont start the radio sound and lights pulse and the starter sounds different/bad when it turns over and the black wire connectiong the coil to the distributer base is split. PLEASE SOMEONE help me I CANT FIX IT please give me any ideas you have.
