new and old sensors

[smilinjack]

Hi All. I've finally got a glimpse of the goal line on my Cleveland project. I'm starting to terminate some final wiring and I have a question.
I have rewired the entire vehicle saving only the original dashboard wiring, the i/c fuse box, and the power distribution box under hood. So far, so good!
I have added new gauges (autometer Z series, all electric) including oil pressure and water temp.
Question is : does anybody know if I can connect both the new gauge wiring and the existing dash gauge wiring to the same (water temp that is) sensor without causing some sort of issue that might cause a faulty signal?? I used a tee for a dual pick up on the oil pressure but don't have the room to do that with the water temp. Thanks

It would be a long shot that the sender would be compatible with both temp gauges.

I bought a hose adaptor that has a bung for the second sender for my aftermarket gauge. Beware that some don't have a ground lug if your sender is a single wire. If it's a two wire sender you probably don't need to ground the adaptor.

38mm (1-1/2") Water Sender Hose Attachment

GlowShift 38mm (1-1/2”) Water Sender Hose Attachments Make It Easy to Install a Temperature Sensor By Cutting the Upper Radiator Hose & Adding the Adapter.

That may not be the correct size for your hose...

Just install another temp sender for the new temp gauge on the heater hose that's on the intake, its the OUT to heater hose

As said by Uncle Gump the metal bung must be grounded for sender to work
Put it as close to engine outlet as practical<<< practical, not possible, lol, not a big deal


Curious about oil pressure sender and gauge, the 1995 dash gauge was setup to only work with an oil pressure switch, on or off switch
Some of the dashes could be converted to use a real sender but not sure on the 1995, you need to bypass a resistor on the back of the cluster, in the mid 1990's Ford moved that resistor to inside the gauge so it couldn't be bypassed

Thanks guys. Right now I've got both new and oem 'single' wires to the same sensor but ran an xtra wire in case I'll need to add that xtra sensor. According to the factory wiring schematic they will ground thru the pipe threads. The only reason I even bothered to include the oem hook ups is because I just wanted the dash fully functioning. Very few things make me crazier than gauges that aren't working!!

Yes, one wire senders were grounded by their theads, if they were installed in a metal part of the engine

The comments regarding grounds was if a sender was installed on a rubber hose, so no ground even if bung is metal
