Adding after market gauges, keep warning lights - how?
« on: February 10, 2019, 12:34:26 PM »
I plan on updating my dash but haven't taken anything apart yet so I'm guess all the warning lights are run off the instrument cluster pcb.

When I add my new gauges how can I add warning lights for the oil, temp, etc that I currently have on my cluster.

Tried searching couldn't find anything - any help is appreciated.

Thanks

It depends on what you mean by that.  To have a light, you need a place to put it and a way to trigger it.  On the trigger/sender side, The oil light sender can be mounted in a tee with whatever is running the gage.  The volt gauge or amp gauge won't interfere with triggering a battery lamp.  They're not related.   Temperature is not as easy.  To have a temperature gauge and light, you need to have two senders inserted.  There are several places on a Pontiac where you could put one, but on some cars you might find that every tapped hole into the water jacket is occupied by something.

There may be some gauges out there with warning lights built in based on the scale.

Thanks, that's what I figured.  It's likely easier adding another pressure sensor than trying to 'tap' into whatever feeds the instrument cluster pcb.

For me the only real one that's critical is oil pressure so a sensor on a t is perfect.

Thanks

Oil pressure is the hardest as there is only one place to tap into and you will need to add a T fitting (which I hear is hard to find). But why do you need both? in my 72 I have a mechanical and electrical water temp (the mech. was there and I added the one that comes with the cluster).

I like having the light as quick notice if there's an issue and I haven't been looking at the gauges

I think that is wise.  An oil pressure gauge really is not that safe.  You are probably not going to notice it.  The sender connections tend to be 1/8" pipe thread but of course you be the judge.  I have re-plumbed a lot of them.

If you’re going custom check out Speedhut’s gauges. Their Revolution gauges include warning lights that you can program to trigger at maximum and minimum values. I have them for tach, oil pressure, voltage, fuel level, and coolant temperature. Gauges include the required senders and harnesses.
