adding a Tach
just want to know if it's hard to add an after market tack? Francine already has the volts, temp, & oil pressure gauges but i gotta replace them, and tho's don't look that hard to do.

The temp and [oil pressure] gauges works by converting temp and pressure in the sender dashpots on the block to an electrical signal and sending that signal back to the gauge where it causes your indicator needle to move.

Your red engine has hei. if thats the engine u have in ur car ur hei cap will say tack next to where u plugged in the positve wire. then the tack will need positive and negative. (and some have an extra wire for the gauge lights)

As mentioned, most tachs now are electric. Got a small one years ago from J.C. Whitney I was able to drill a hole right into the dash of my car. My car has MSD 6AL ignition, so needed one of their tach adapter modules. For the three gauge pod, got a small Auto Meter electric unit from Summit racing, in a black plastic bracket, with black bezel gauges. Should be perfect for you. Actually had a paint supplier mix me up some satin red paint for the bracket to match the interior, and about good as it gets.
