[V8] "Major Surging"

[dsaad at icehouse.net]

Since you have a need to replace connectors, It would probably make sense (and
cents) to choose a particular O2 sensor - either a 3 wire or 4 wire, then get
the mating engine side plug and splice it into your system. Remember if you go
with the 4 wire, you need to add a ground wire. This way you can buy off the
shelf Ford sensors and plug them right in. This is what I have done.
To get to the wires, you will probably have to remove all the air box stuff to
gain easy access to the wire harness.
