1991-1996 B-Body LS Gauge Components

Gauge hookups for a 1991-1996 Caprice, Impala SS or Roadmaster that now runs an LS. One part converts the distributorless LS ignition into a signal a traditional tach or shift light understands. The other is an adapter fitting for a traditional oil pressure gauge sensor.

You supply the wiring between the tach adapter and your gauge; this listing ships without the BRP LS harness.
Both gauge parts are general LS swap items, the same ones BRP offers on its other chassis pages.
The 1991-1996 B-Body guide talks about mounts, A/C brackets, oil pans, transmission tunnels and headers. Gauges are not in it.

Part details are taken from the BRP product listings. Fit notes for the car are in the 1991-1996 B-Body LS install guide.

1991-1996 B-Body LS gauge FAQ

How do I get a tach signal from an LS in my Caprice or Impala SS?

Use the Tach Adapter. It is made for distributorless ignition systems and controls a factory or aftermarket traditional tachometer or shift light.

Does the B-Body tach adapter include a harness?

No. It is sold without the BRP LS harness so you can wire it to suit your build.

Which fitting lets me run an oil pressure gauge sensor on the swapped LS?

The Oil Pressure Adapter Fitting. It allows a traditional pressure gauge sensor to be used with the LS engine.
