When installing new O2 sensors, do I have to unplug anything so it doesn't mess with the computer? Putting in Bosch sensors with extension harnesses on my long tubes...Thanks

i don't think so but u can unhook the neg battery cable just to be on the safe side if u wish too. what lt's did u go with i got the BBK with the wire extensions as well

always disconnect the neg. battery cable before changing any kind of electronic component on your car. this resets the computer so it can "learn" it's parameters again with the new parts and protects you from shorting or damaging anything.
