Fixing the wiring of my tach - I'm dumber than a blonde!

Here you go.
Probably the toughest part is to find 12v switch power.
Go to the fuse panel, and unscrew the screw to free it up.
Get a test light. Hook one end up to ground, and touch each fuse turning the key on and off.
That is how you find a 12v switch power. Usually there is a piggy back terminal where you can connect the 12v to switch wire to. The same test is used to find the headlight fuse. This is the fuse that the white wire hooks up to.
Hope this helps.
