1970-1972 Monte Carlo LS Gauge Parts

A first gen Monte Carlo with an LS still needs a working tach and oil pressure gauge. The LS uses distributorless ignition, so the tach adapter makes an rpm signal a traditional tachometer or shift light can take. A separate adapter fitting lets a traditional oil pressure gauge sensor mount on the engine.

Monte Carlo gauge notes

Wiring is custom. BRP leaves its LS harness out of this listing.
Both parts are universal LS items. BRP did not make a Monte Carlo-only version.
The 1970-1972 Monte Carlo guide covers tunnel work, crossmember and headers, not gauges.

The part details are from BRP product listings. See the 1970-1972 Monte Carlo LS install guide for the chassis side.

1970-1972 Monte Carlo LS gauge FAQ

Can my 1970-1972 Monte Carlo keep a tach after the LS goes in?

Yes. The Tach Adapter turns the distributorless LS ignition into a signal for a factory or aftermarket traditional tach, or for a shift light.

What comes with the Monte Carlo tach adapter?

The adapter only. The BRP LS harness is not included in this version.

How does a traditional oil pressure gauge connect to the LS?

Through the Oil Pressure Adapter Fitting, which lets the LS accept a traditional pressure gauge sensor.
