1968-1974 Nova LS Gauge Components

Two small parts keep the dash useful in a 1968-1974 Nova or Ventura with an LS. One gives a traditional tachometer or shift light an rpm signal it can read, since the LS fires its coils with no distributor. The other lets the engine take a traditional oil pressure gauge sensor.

X-Body gauge notes

No LS harness ships with this tach adapter. It is meant for custom wiring.
These are general LS parts, not Nova-specific pieces.
The X-Body guide sticks to mounts, oil pan, headers and the A/C bracket. Gauges are not in it.

Part facts are from the BRP listings. For the rest of the swap, see the 1968-1974 X-Body install guide.

1968-1974 Nova LS gauge FAQ

Can a 1968-1974 Nova keep a traditional tach with an LS?

Yes, with the Tach Adapter. The LS has no distributor, so the adapter produces a signal a factory or aftermarket traditional tach, or a shift light, can use.

Does the Nova tach adapter come with wiring?

No. BRP offers this Nova-page version without its LS harness, leaving the wiring layout to you.

How do I add an oil pressure gauge to an LS Nova?

Install the Oil Pressure Adapter Fitting, then thread a traditional pressure gauge sensor into it.
