Not sure of how to hook up tach
 

Black wire is ground.

Green wire goes to negative (driver's side inner fender) of coil.

White wire goes to dash lighting fuse in fuse box.

Red wire is for constant power but I'm not sure where that should be?

If I have anything wrong or if you have better suggestions, please tell me.

I have the constant (red) and the switched (white) tied together. I have it mounted to a togle switch along with the rest of my dash and it works fine. The tack dosn't loose it's memory either.

red to 12v switched (ex.-radio hot)probe out wires with a volt-meter or test light.

saltz is correct. Run the red wire to a source that is only switched on when the key is in Run. There are numerous sources in your fuse box.

White - dash lights (ashtray light, HAVC light, etc.)

Green - neg. side of the coil

Black - ground

I appriciate the help guys, just one more question. I was looking at the coil and noticed it is a plug in with 2 wires. I'm guessing the green one which is closest to the inner fender is negative. Do I just splice into that? Or are there any oter alternatives to that?

Yes, the green wire is the negative side of the coil. Just use a 3M splice connector, and attach the tach wire to the green wire where ever it is most convenient.

Take care,
