    Aftermarket fuel gauge?

    Long story short.. 05 CTS 3.6. Im wondering how I can run an aftermarket fuel gauge as Im building my own custom cluster (hey that sounded good)

    Seriously though, two senders.. each going 40 to 250 ohm. Weird thing is you must have both sensors for an accurate reading. Another weird thing is that according to a service bulletin 250 ohms reads full!?? (most aftermarkets run 40 ohm full)

    Which wires at the cluster run fuel level?

    Any advice on wiring up a gauge?

    Thanks!

    if you wanted to you could use the OBD port via a bluetooth dongle (wifi for iphones) to send live data to your smartphone (android), engine temps, intake, fuel level, estimated mpg, coolant temps etc, probably a little simpler, otherwise *shrugs shoulders* lol

    I seriously think the easier option would be to leave the stock ones be and enjoy the car lol, to much electronics to mess with which is why responses have been very few and far between.
