Ok, ive heard lots of different answers but no straight ones. Does the 98 cobra's have one or two temp sensors? i replaced the on the left side crossover but my temp guage still doesnt work. Can someone please answer this??
98 Cobra temp sensor questions

One is wired directly to the PCM and the other is wired to the factory gauge.
Both of them are in the coolant crossover. One on the pass side one on the drivers side.
Oh and on a side note they are not the same sensor. One has a pointed tip and the other has a flat tip.
The red wire with the white stripe is the gauge sender. The light green wire with the red stripe is the PCM sender. I have seen them on both sides of the crossover pipe, so you have to check the wire colors. The connector bodies are also color coded. On my latest junkyard find, the gauge sender and connector bodies are green. The PCM sender body is white and the connector body is gray.
If there is no bung ont he crossover or you cant find the sender then someone has replaced the coolant crossover. The 96-97 cobra crossover only has 1 sensor I do believe but I could be wrong. Are you able to take a picture and post it on here.
Hmm maybe its a Mk8 or 99 up coolant crossover. The previous owner could have needed one and not been able to find a 98 cobra replacement and replaced it with whatever they had. You can also the the other sensor and screw it into the place where the plug goes on the crossover.
96-97 do have 2 sensors . but they are 3 pin sensors where the 98 is a 2 pin
In my 96 Cobra, the PCM sensor is a two pin connector, and the gauge sender is a one pin connector. Sometime near the end of 97 Ford went to a two pin connector for the gauge also. I suspect it was because the one pin sender depends on the crossover pipe having a good ground to the engine, not something that is always there. 98s have the same crossover pipe.
99+ crossover pipes only have a PCM sensor. The PCM sends the temperature data to the microprocessor in the instrument cluster via a data bus and it then points the gauge needle in the correct direction. It sounds like you have a 99+ crossover pipe.
The sensor will not fit in the crossover cap hole. I'd do the latter if I were you, although I do have a new crossover cap drilled and tapped for an Autometer sender: New Coolant Crossover Tube
Lol thanks mark. I was hoping I didn't have it backwards. I couldn't quite remember our conversation

OR you can get a (1) male-to-(2) female tee connector, and do sometihing like this:
This setup is two stock ECT sensors attached to my Vortech crossover tube. Your physical arrangement may be different.
Fyi- I have a 97 and it has two temp sensors. They are both pointy. The junk yard vortech crossover pipe I bought has two temp sensors (one pointy and flat bottomed). My car was built in November 96.
