    Check engine light came on recently for my mass air flow sensor. One of the wires connecting to the sensor has come apart. Seems too short to solder as there is no slack at all. Does anyone know of a new wire harness I can get and install?

    U sure thats not a wire bundle further past that clip (to the right)?

    Id be peeling back that tape/plastic sheet.

    Then solder in a piece of copper wire between em...

    Same concept as the maf extension for the urd intake back in the day

    hell you dont even need to solder a extra piece in there. disconnect from the sensor, open the wiring harness slightly and either solder them together or butt connect them. make sure to put heat shrink on the wires before connecting them. if you decide to use a butt connector you should use a uninsulated one and then once crimped slide the heat-shrink over and use a lighter or hairdryer to shrink it.
    if you use a lighter place a piece of cardboard between that wire and the rest so you don't risk melting their insulation.

    Thanks for the replies. I'll try using a butt connector and shrink wrap

    just so we are clear when you say shrink wrap you do mean this heat shrink.jpg and not this shrink wrap.jpg correct?

    Ha yes, heat shrink. Electrical stuff is not my forte.

    ok just wanted to make sure, customer had wired up some halo lights that had wires simply twisted together with electrical tape very loosely would around them.

    Crimp them good... gadget does not suggest butt connectors for the maf calibrator due to problems in the past. Maf calibrator is not the same thing we are talking about, i know.... but i assume the sensor may be effected by subpar connections and or resistance.
    I was worried about solder even, but in the last 5yrs of the maf sensor harness being extended with solder, ive yet to have an issue.
