I would do a resistance check first to make sure it's grounded and not shorted.

There is a link in my signature on ho to do this.

82JeepCJ7 Did you put it in with teflon tape?

turbogus If you're going into the temp gauge anyway, if you've got the flow you may consider a wide sweep gauge;

wglikes Where did you purchase the temp gauge you show in the picture?
Thanks

That black wire from the bulb also goes to ground.
This is exactly right.

Looks like the Meter can be used on either + ground or - ground vehicals.

Looks simple enough to attach the black wire to the - post and then run a wire from the - post to a ground screw on the dash. Either make your own grounding point with a self tapping screw or the speedo mounting bolt on the back of the dash.

Run the + post to the "I" terminal on the back of the fuel gauge like Bagusjeep mentions.

Run the red wire on the light to some orange wire on the back of the dash like 82JeepCJ7 says


First time I ever saw a gauge with metric and English markings like that though.

82JeepCJ7 Usually the gauge lights are powered by an orange wire. Look at a few other gauges to see where they get their power for the lights. It should vary in voltage when you turn the headlight switch left and right.

The power was a shared red wire, there was one connection for the fuel and temperature gauge. It is unknown as to where your power is coming from for the new gauge but I suggest finding one that is linked to the IGN LPS fuse in the fuse box, probably red.

I am not very confident on the factory gauge that it works as it should as it seems that it stays in the same spot most of the time and Jeep does not have an overflow tank. I plan on buying an Auto Meter gauge and installing that to get a more accurate reading of the temperature that I am running. Any help would be appreciated. Thanks

Splitting hairs really, but I wouldn't have the room on the boss that's on my t-stat housing to put one.

CJ8Extreme Ah I got ya, I've always needed my overflow tank . A cheap infared Thermometer from Autozone for 10 dollars will give you a quick reading on your temp under the hood. I keep one of those around in my glove box to help track down problems under the hood.

The last autometer gauge I bought just required finding a place to mount the probe for the gauge. I tappd a new hole for the probe near the thermostat as mentioned above. For ease you can probably use the orginal hole in the back of the block if the threads are the same, I can't vouch for that mounting spot because I did not use that one.
