Replacing oxygen senser,after market sensor has to be spliced to old sensor plug. Wires on old plug has 2 brown,1 tan 1 purple wire. New sensor has 2 white,1 black,1 grey wire.My question is what wires should be spliced together?

Hi there,

with out knowing what brand of O2 sensor you have, theres no way of knowing what is what, even with that info i may be hard to track down the wire code.. is there anything on the package re instructions...

take it back and go get a GM one, your only going to cause problems in the long run
