k, so i just tried to put a instrument cluster into my 86 bII, i found a cluster with a tach in it and wanted it. got home and started to hook it up. got it all done and started the truck, tach don;t work. and when ever i turn on the lights the fuel gauge and temp gauge go to maximum.

does anyone know what wires i need for the tach to work, or where to splice into???
and why the gauges get screwed up when ever i turn on the lights?

thanks
