Oil pressure gauge and idiot light
 

72 C10 does not have oil pressure gauge hooked up.
Not sure if I can, but would like the mechanical gauge and the light to both work.
Has HEI, and from what I read here, that prohibits the tee connection for the 2 in one.

Can I do the mechanical from the back of intake and the idiot light from over by the old filter on this 350?

Where do I send the wire to from the sensor for the light?

Thanks

I don't see why you can't use a tee with HEI. I've used electric oil sending units with HEI (which are pretty large) and have had no problems. I can't help with the light tho.

You can use both:

Either by the dist or by the oil filter.

The problem is no place for light on full gauge cluster. You could place it where the temp light is in the gauge gauge and change the filter to say oil instead of temp, wire accordingly and it should look factory and work.

Tbone, could I tap into that temp light and have it light up for both? High temp and low oil pressure?

What activates that temp light now? None of my gauges worked and were not hooked up excpet for speed, so am starting from scratch.

Use a tee for the sender and oil line. Get a no gauge under dash harness and pull the wire that would normally run to what is now the empty idiot light in the fuel gauge of a gauge cluster that is a used light in the non gauge cluster. There are empty pin locations in your gauge harness that will accept the no gauge idiot light wire and the trace is on the flex circuit to that location. Do the same with the under hood harness. You can then use that indicator light as a check engine light. I installed the idiot light sender into the other head and tee'd the oil pressure and temp senders to that same light. It is ground activated by either of the two senders. If the light is on I look to the temp and oil pressure gauges for a problem.
