THe red goes to any switched power source under the hood. There's a fuse box right behind the battery that if you do a little checking you'll find a switched source. If you look at the coil packs on the driver's side you'll find a common colored wire on each connector,I don't remember the color but that is the GROUND for each coil. Use the opposite wire from one of the coil's.

Oh,and the tach,SHOULD have red-constant power,yellow-switched power or illummination(turns on the back light),black-ground,and (typically) green which in signal input(connect to the grey on your tach adapt.)
