They are all pretty much the same, i have cut and crimped heads from different number BOSCH sensors provided they have the same number of wires ie 5 wires are wideband narrow 3. Never solder as this prevents atmospheric air from getting down into the sensor head needed by the sensor to calc the diff between normal o2 in atmosphere and that in exhaust gases. I have tried it and you get a code with solder (!) which seals off the fresh air supply from traveling down between the insulation and wire - hard as it is to believe from looking at the wires!
