I just took advantage of the sale at cpperformance for the platnum gauge set. I got the tach from livorsi and it has a sticker on the side indicating switch placment between 4 6 and 8 cylinder engines. Where is this switch? Is it just plug and play or is does this not apply to my application? Just wondering if i need to take it apart and set these switches to the appropriate position... If there is even switches contained in the unit.
