Hi Volks,
    You can insert a heated oxygen sensor (3 or 4) wire  most anywhere in
the exhaust, before the cat of course.  Wire the heater white wires  to coil
plus and ground the other. Wire the black to your ecu input pin, ground the
gray wire if it is a 4 wire sensor.  I run an 81  California van L-Jetronic
system on my 78 westy and love it, always a near perfect mixture. No more
fiddling with the afm (air flow meter) spring tension to get a proper
mixture.  It is a 78 national and came new without a cat so  I have the
oxygen sensor installed just past the muffler on it.
