    im tired and tired of looking, on a honda crx 90, does it mater where the 4 wire o2 is installed , should it be on the top of the manifold or at the end before the cat, i was told i dont need 2- 4 wire o2 sensors i can use 1- 4 wire and the stock one from the crx as my second.

    im using a p28 with the obd1 harness and sub harness:rolleyes:

    You could use your CRX motor exhaust manifold that has the O2 hole in it already.
    And yes OBD1 only needs 1 sensor as ahhvtec stated. Or does the Z6 mani already have the hole?
