Here is some info:
On most tach there are 4 wires.
Green wire that is for the tach signal
Black Wire for ground
Red wire for Power to gauge
White wire for ligths for gauge
On these cars the OBDII scanner port is just under the dash 16 pin connector. first pin on bottom row, left to right is for the tachometer. The rest of the wires go on the fuse box. Ground wire attacth to good metal ground under dash. Hook the wire that turns on the gauge to the ACC fuse. . And hook up the wire for the lights tp your taillight fuse. Be careful, Make sure you connect this right or you might screw up your car.
Hope this helps
