in this one u can see both wires commin from the coil red "hot" green and yellow strip "ground"
in this one u can see i used a splice conector like what u use when hooking up a trailor harness
my tach had 4 wires red "hot" black "ground" white "light" green "to coil"
i hooked the red to the empty costant hot in my fuse block i grounded the ground to the e-break braket and i hooked the light into the dash light so when u turn the lights on the tach light comes on
in this one u can see ware i mounted my tach its out of the way but still easly seen plus it was easy to hide the wires going down into the kick pannel
also when u do this use a razor blade to cut the tape off the case on the coil wires but becarfull not to nick the wires

A clip each for the h/l & wiper *****, a few screws for the cluster bezel, unplug the tank & other switches (if equipped), pull 2 screws & drop the shift indicator (if equipped); 4 screws, 2 connectors, & the speedo cable, and the cluster comes out. At that point, you can either splice the tach into the cluster wiring, or just plug in a tach cluster, then put it all back in.
