multiple coolent temp sensors

[LQQKatJon]

years back, I removed the christmas tree vacuum switch, and installed a analog coolent temp guage/sensor. it was very accurate and served me
well for many years.

When I installed my EBL-EFI system, I pulled that sensor out, and left it dangling on the manifold with a zip tie. and used that spot to install
the sensor for my EFI system.

I am now having some issues with the EBL whats up display, and without that the only temp display I have is the original dash gauge that is still
located in the stock location.

I want to install the analog sensor again.. I have not removed the gauge itself. but I don't want to loose the stock sensor, and I can't loose the
efi sensor. has anybody found a Y, or does a person just go buy a bunch of crappy brass parts and make some sort of T fitting? I don't want to
make any higher of a spot for coolant to be off the manifold.

what happens if you T off he electrical sensor to feed both the EBL and the stock gauge? I am guessing that won't work right?

You could also easily drill a hole into the manifold and tap it for your sensor.
My manifold had a round flat spot on the driver’s side front top which I drilled and tapped for a sensor a few years back when I installed a Digipanel.

That sensor needs to ride in the coolant. I do not like the tee idea because any air passing by the tee may get trapped in the Tee and cause sensor
errors.

Since the OEM dash temperature gauge is not that accurate, how about removing its sensor and installing your aftermarket gauge sensor in its place and
ignore the dead dash gauge.

Another idea is... the Digipanel uses a bolt-on sensor which is fastened to one of the thermostat housing bolts. The Digipanel seems to be fairly
accurate. I'm not sure if there is a bolt-on 90 ohm GM type sensor available, but if so it would likely be accurate enough for your OEM dash temp
gauge.

I agree with Ken, and that is why I don't want to rig up some plumbing to T a couple sensors in. I also hate disturbing too much stock stuff,
like having a temp gauge on the dash, even though it is kinda useless, to be dead. I will probably pull the stock sensor out to install the analog
one, and that will get me an accurate reading of what I want to know off the analog gauge while I work on my whatsup display temp. There is
sometimes I have not had the tablet on too, so it will be nice to have an accurate always on temp reading. I found the need for that when my fan
clutch acted up last year.

I also am thinking now that if I can't find a way to get a reliable reading off the front of the manifold, I could put a sensor into the radiator
for the dash.

With my future (warmer) weather install of the Mercedes fan, I'll be adding a sensor in the lower radiator hose using a fitting similar to this:
