IIRC, taking out the stock temp sender will mess with the computer, because it does take water temperature into account. It also uses the original sender to know when to turn the fan On and OFF.

Does the Autolite sender have the same ammount of wires coming out of it ? (I cant remember how many wires the stock Temp. sender has coming out of it.. sue me :p )

If it does, maybe you can tap the new gauge into the Original sender.

You don't want to be adding any additional gauges to one sender, as this will mess with the signal (ie resistant to ground). This happens cause you now have two gauges trying to put the resistance to ground and measure it, if I remember right you'll actuallly end up reading higher than what it's really at. We went through this problem at work when we installed a couple secondary gauges into a de-ice truck. Wound up having to install a second sensor.

the sender does tell the computer how warm the engine is, that way it can make a better a/f ratio. As far as where to put the sender...I couldn't tell ya, I'm still using the stock gauge.

Ok, this is what I've been able to come up with.

The sensor on the Thermostat housing goes to the Dashboard gauge. The other sensor that sits at a 45 degree angle and screws into the manifold is also a temp sender, but that goes directly to the computer.

So, I would think that if you take out the Sender from the Thermostat housing, and put the aftermarket sender in its place, it will work just fine. Just remember to ground the OEM sender wire, otherwise you will get a "Check Gauges" light... I would presume... I will update when I get my water and tranny temp gauges. I might even take a few pics.

Ok, Above is correct.

I just installed some gauges a couple of days ago. The water gauge sender goes into the T-Stat housing. You will need a 3/8" Sender, or a 3/8" to whatever size sender you have nipple.

You can leave the OE wire un-attached. It will not throw any "check Gauges lights" or and CEL's.

I'm thinking of running the OE sender to the Radiator, and plumbing it in thee. Not very accurate, true. But it's better than having it sit on "C" all the time.

I just added a T so I could screw the stock sensor back in and then plumb the new sensor.
