Looking for a little help or advice on installing a tachometer on my 66 barracuda

I am having trouble with the white light wire. Where should I connect it or where is everybody else?

Everything else is done and connected

thanks

Use your 12V test light and splice it into the dash light harness. That way, it will turn on and dim along with the others.
