From Idiot Lights to Guages

[72stepside]

I have an add on ammeter and oil pressure guage. Of course my instrument cluster has the idiot lights. Today at the junkyard I got a cluster with the guages in leiu of the idiot lights.

What are the requirements to switch to guages? New oil pressure sending unit? Anybody got the part number (due to idiots at the parts store)?

I would like to eliminate the add on guages mainly due to the little small tube running through the firewall, full of pressurized oil. It hasn't caused a problem... YET !!

The ammeter in the full-instrumentation panel will not work as-is in a truck originally wired up for an idiot light. The ammeter uses a shunt in the front harness to supply power to the ammeter, plus there are a couple other minor wiring differences. Do a search here for 'shunt' and you'll see where this has been discussed a few times. Here's a few threads to get you started:
