Water temp gauge
I want to hook up a autometer water temp gauge. The question I have is can I hook it up to the factory sending unit and get an accurate reading or how do I have to hook it up? If there is another way that I have to hook it up, what will I need?
Thanks
Thanks

Yo! Z! Go to this site http://www.xse.com/leres/ss/gaugepod.html This will give you all the information you need. I used the adapter from Auto Barn and installed a sending unit at the #8 plug which is at the rear of the passenger side head. This works much better than the "broken" stock temp guage.

You will need an M16x1.5 adapter to go in this hole. Tapping off the stock sender will give you the same dummy results, and even mess up the readings by trying to split the signal voltage between two gauges...

MOBE, I tried the bottom of the block and the temp readings were off by more than 20* as measured by my Predator; I.E. - The temps were too low. The "Hole in the Head" is more accurate. But I do agree with you about the water pump. I hope this helps.

nobody can answer the stock temp sender question.
the 98 sender is 2 senders, in 1, 3 wires, 1 to ground, and that goes to the factory gauge, and the other 2, go to the computer.
the 98 3rd wire, has been tested, and is the same calibration as the autometer sending unit.
the 99+ goes to the computer only, and is 2 wires, the gauge cluster gets the information from the serial data bus from the computer.
in theory, if the other 2 wires to the computer, are the same as the 99+ temp senders, you could simply install a 98 sender, and get the wiring harness, splice this to your computer, and use the third pin, to the aftermarket gauge.
Anybody know if the 99+ sender is same calibration?

I had the pump off during a head swap, so it only took 5 min. to install it there and I didn't need any stupid metric adapters or anything either.
