I just got done installing my tach and it DON'T work. the lights work, it's got power to it, when i turn the ign on the needle goes to 0 and then to 1 and after starting the car it don't do anything. the needle only moves when i move the SHIFT-SET dial. I double and triple checked all my connections. how would i check the two tach wires in the engine bay to see if it's sending the correct voltage to the tach? and if they are no good what wire would i tap into coming from the ecm? the only thing it's NOT doing is getting the info from the tach connector. thanks, scot w.
