    Ok there is tons and tons of info and pics and charts on what you need, and how to
    drop the gsr/ b16/ b18 into the crx/ ef.

    But what I dont under stand is there is little wiring help with this.

    I found pics on the the ecu im using. Not exactly sure if the 88 and 89 have the same
    wire codes. But I found the 88.

    And I have 2 complete wiring harness's. The original ef and the ls/v wiring harness.

    But there is so many more sensors. Not exactly sure on how to run this. Well any help be helpful.
    Thanks in advance.

    There is only 4 sensors you have to add.
    VTEC
    IAT
    Knock
    o2

    It's not as hard as your making it seem.

    Just use the ECU that goes with the head.
    Get a obd-0 to obd-1 conversion harness from Boomslang.us. (comes pre-wired with all those nessesary wires)
    Then just install.

    It's not that bad...

    hmm, well im running a obd1 gsr head, and a p28 ecu.

    you know that sensor right in the back by the alternator
    that has two plugs that are right next to each other and
    they have no markings on them. Does it matter which one
    is which?

    Nope. It doesnt matter.
    That is your coolant temp fan switch. it doesnt matter which one goes on each prong.

    where does that big fat white wire run from the alternator?
    and does it matter that the plugs are wiried differently or do the
    ecu jumpers take care of that.

    The ECU jumpers convert the car's harness to plug straight into the new ECU. Rywire.com also has great products.
    The Alternator wire runs into the fusebox.
