    I bought an outside temp gauge and was wondering whats the best way to install it. I want the gauge to have power when I turn the key switch like the rest of my gauges. I'm thinking running the power to the fuse box with a spare fuse, how big of a fuse should I use? It's going into a 99 peterbilt..thanks for any advise..

    Hello brenes-built,

    This will be a pretty straightforward installation. To begin, using a test light or digital volt meter, locate a spare fuse holder in your fuse box that has power when the key is turned to the "Run" Position and then does not have power when the ignition is turned to the "off" position. This will be the power supply for your gauge.

    According to the specifications that I found online for the TelTek Temperature gauges, you should only need a 5 amp fuse for this circuit.

    Before proceeding, make sure that the ignition key is off.

    Now, gain access to the back side of the fuse box and attach your power wire to the terminal lug opposite the powered lug that you just found in the previous steps. Run your power wire up to the backside of the dash or where ever you are going to mount your gauge, making sure to route the wire in a manner that will keep it out of harms way. Do not cut the wire to length just yet

    Next, mount your gauge, if it is an in-dash gauge, remove your gauge panel and install it in on of your blank holes as per the instructions that came with the gauge.

    Then, find a suitable ground behind the dash which will be a bolt that has other ground leads secured to it or find your own ground in a screw or bolt that is screwed directly into a grounded metal part behind the dash.

    Once you have your ground wire secured, run the wire up to the gauge location, but as with the power wire, do not cut it to length just yet.

    Beginning at the fuse box and the grounding point, begin to fasten the wires with some wire ties so that they cannot chafe or be cut while you are driving. Once you have fastened the wires and now can see exactly how much wire you need to reach the gauge connections, hook up the two wires to the power and ground respectively. Finish securing the wires with wire ties if needed.

    Finally, attach the temperature probe to the back of the gauge housing if it is not already plugged in. Then run the temperature probe to a suitable location as per the suggestions on the gauge instructions. Again, fasten the probe with wire ties.

    Once that is complete you can reassemble the dash panel and any other panels that you had to open in order to perform the installation.

    Install a 5 amp fuse into your newly run circuit and close the fuse box panel.

    Turn the key on and enjoy your new gauge!

    Hope this helps...

    Awesome response. Only thing I want to be clear on is on the backside of the fuse box there will be two lugs, connect my wire to the one with no power.. Is that right, I'm guessing so that when I put in the fuse I complete the circuit...thanks for your help..
