    passenger side floorpan, pull the carpet back and there it is. Jump the 2 pin plug with a small piece of wire, but im not sure where its at on the CB7, sorry.

    you don't need to jumper anything - just look at the flashing red LED on top of the ECU and count the flashes

    Exactly my thoughts as well, my 92 lx didnt have the check light but had the jumper plug, and the codes were checked on the dash like a civic.

    Same way in this thread

    and here

    several other sites say the same

    http://www.google.com/search?q=how+to+check+1991+accord+ecu+codes&hl=en&start=40&sa=N

    These guys know better than anyone

    There is a jumper if you dont have a light on the ecu. I would look for a jumper first, if its there its a 2 pin plug and probally blue.
