Where did you splice it in exactly? I've done the same thing and am getting some random readings from my Autometer Gauge. I am on the down-slope from the highest point of the radiator hose, with the sensor in the 6'oclock position. Im thinking about moving it to just before the inlet of the radiator.

I did this when I ran external gauges
It's the plug on the bottom of the intake manifold. Vehicles other than Discovery used it, but its a blank plug that takes a lot of force to remove the first time. Bored it to clear a socket, then tapped to 1/8" npt. Bored the back for coolant to get around the sensor.
Since it is NPT you could probably get away with a drill if you didn't have a lathe, but I wouldn't want to do that.

The temp sensor on my '96 is in this location. I just used a bushing rather than drill and tap the plug.
The one in my '94 uses the inline hose adapter, 38mm.
I'm running different gauges in each truck. The one in the '96 seems to read about 10 degrees cooler than the ECU reading.

have you compared the 94 temp gauge with rovergauge?

New option for gauge mounting

that one looks rough because it was printed on a cheap $400 printer. The shapeways stuff looks really good and is much more durable than printed ABS
