You guys using aftermarket water temp gauges, what are you using (brand)? Where are you getting your signal from without replacing/interrupting the factory water temp signal to your MS?
I've got an autometer phantom water temp gauge that was given to me, its electric short sweep style and I need a temp sender for it but I dont want to interrupt my water temp signal to my MS for obvious reasons.
Help?

Stock, linearized.
On all Miatas 1989-2005, the dash gauge and the ECU are fed by two different sensors. In the '99 and later cars, these two sensors are in the same housing, but are still electrically isolated.

Joe, I just did a quick search under you name. Searching for linear, water, coolant, sensor, etc. and could not find a thread showing your linearaztion of the gauge. Not that I could do it anyway. Electrical moron here. Anyway one of these days you and Abe need to come up to the Bear, for some mountain biking. There will be tons of good beer, fish tacos, and you can do your magic on my car, making it super bitchin. Just let me know, I'll start grillin.

Im assuming the sensor on the back of the head near the heater hoses is just a gauge sender and not an ECU sender? If so can I just splice into that sensor with the gauge signal wire and get a signal or do I need the autometer sender.

I recently installed this SPA Design dual oil & water temp gauge. The water sender is in the spare port of the M-tuned reroute housing on the back of the head. If you don't have a pre-tapped reroute housing, you can use one of the radiator hose adapters, or a similar style of adapter sized to fit the heater core hose. Pegasus sells both sizes.

The gauge seems to read about 10*F low once the car is warmed up, but it has a service menu that you access with the push-button (hidden away) that can supposedly be used to manually calibrate it. I haven't gotten around to messing with it yet.

The sensor itself is fairly linear, but you can't just feed it into an aftermarket gauge- the calibration is wrong.

Oh, and if you put the sensor where spookyfish did, you won't get accurate readings while the thermostat is closed, as there won't be any flow past the sensor.
