09 engine coolant temperature gauge

Recommended Posts

So I was driving truck today, started up a hill and flipped on my engine fan because the temperature was going up... and it just clicked. These 09's have an engine coolant sensor, so why in the world couldnt we add a little gauge so we can see what it is???

I realize it wouldn't just be a t-tap into a gauge, but seems like we could take the signal going to the ecm, modify it and run a little temperature gauge. Maybe it would be to much work but I think I'm going to try and figure something out. I'm not a huge fan of the little temperature strips and this seems like it would be much more accurate. I ride the sand dunes often in the summer and fall and it would be way nice to just look at a little digital number and say "time to back off a little".

What are your guy's thoughts?? Any suggestions on where to start, or where to find a mini temperature gauge?

Nothing really... just know that it has one. Thats why I'm asking, so see if anyone has some good incite about it.
