    seeing that the oxygen sensors are too short to even reach the header or cat that I will buy in the near future, I was wondering if they are sensitive to soldering? Will they function the same? Or not? I was just wondering cause I dont feel like paying a shop $100 plus to extend the wiring. (1996 civic hatchie DX)

    Get some wires and solder them on. I ve heard you need a shielded wire for the signal, but have seen people successfully do it without.

    what do you mean a sheilded wire?

    i gotta extend my o2 sensor to reach the downpipe next week.
    all i was told to do was to get 18 gua. wire, green, two blacks and red?
    and cut and splice....on a obd2 civic...


    is that right?

    oh....and what about piggybacking my ecu with the blue box fmu from greddy?

    do i HAVE to solder? or can i use those "crimp connectors" or whatever they are called?

    You can get away with just the crimp connectors, but do you really want to?

    i used crimp style connectors and no shielded wire and it's fine..

    the shielded wire is mainly used for the knok sensor

    As Pils said he didn't, I didn't and I can dig up others that haven't. But a soldered connection is more solid, just a perfectionist thing.

    so in terms of how the current runs through the wires, crimp connectors are ok?

    where can i buy them from and what size? would i need to work on the ecu?
