I'm guessing you have the newer 3-wire sensor (if it's a 1-wire and u need
help...hoo boy!). I just put a new bosch 3-wire on my own myself. Cut the
wires off the old sensor. Cut 'em off close to the old sensor so you have
plenty of length. Now get out the new sensor. The two white wires on the new
sensor are the heater. They connect to the two wires on the rectangular
connector. Polarity doesn't matter. Butt splice those together. The black
wire goes on the remaining wire, with the single rubber booted spade
connector on the end. That's all there is to it! Before splicing anything,
you may wish to slip a length of shrink tubing over the wires to cover the
splices.
