Been using the delco 3 wire,running 1 white to ground,1 white to hot then purple to ecm.I've got 2 new 4 wire O2's and wondering if I could hook them up?2-white wires,1 black and 1 gray.Where do they go?
 
Caspers make an adaptor for the 3 wire to 4 wire oxygen sensor.
I believe it is $15.99 or $19.99. Check their web page.
