Okay, so I'm in the process of installing an aftermarket tach..Power and ground wires were easy, but the white wire needs to splice with an instrument lamp( dimmer control) && the green wire need to splice with the tachometer output lead???? I am clueless to where these wires are located... I'm not asking for your opinion on the tach JUST how to install it haha THANKS

 

Hook the light with the ignition wire together, the tach lead is at the ECU.


Now I'm giving you my opinion regardless if you want it. WTF are you installing some huge cheap *** tach that is more inaccurate then the stock on? By the looks of things you either won a shopping spree at pep boys, or abused the employee discount at autozone.
