    These are so easy to make it is a joke. Here is the one I made to power some sensors. You don't need the heat sink I fitted in the photo. I was just testing if I could wire up my sensors without it getting hot. It didn't get hot.

    Here's an Allpar article, too.

    Why the three capacitors, Roppa?

    I'd buy the RT eng one.  I built 1 like suggested in Mopar article, it never worked well.  If you do the calculations you'll see it can't supply enough current.

    Each of the 3 gauges has only 4-6ohms of resistance at the extreme.  So it has to supply 5V/(5/3)ohms  = 3A.  The regualtor is only rated up to 1A.
    I even put a heatsink on mine, it does get extremely hot, still not good.  My oil pressure gauge never worked right, went back to the stock unit and all it fine.

    Seems to,

    You can PM me some details and I can forward it if you want.  But I bet if you log out and try again it should work.
