    Seriously, where in the reference is the CEL code chart with a good detailed explanation on how to check CEL codes on the popular honda's?

    This seems like it owuld be a given to have on here. Hell, I didn't beleive my friend when he told me that he couldn't find it when he was checking his CEL's the other day.

    I am tooooooo lazy to mess with it, sorry. I'll just play informant. :p

    EDIT I was helping check codes on a Skunk2 Chipped P30 in a b16a swapped Del Sol S that looks just like B's car, only faster.

    Here's a handy chart for pulling your ECU codes. Pulling the code is a fairly easy process.
    For 92+ Honda's and 94+ Acura's:

    Before you can start reading the CEL (check engine light) in your dash, you need to 'jump' your ecu. Here's how.
    Located the factory two-pin connector of brown and black wires near the ECU on Civics del Sols and Integra's, or behind the center console for Preludes and Accords. Pull that 2-pin out of the main harness. Using a wire or paper clip as a jumper, connect the outputs of the harness together, so that the black wire and the brown wire make a circuit. Once this is jumped together, the dash will start the light show, so its a good idea to jump first, then turn to on.

    For 88-91 Honda's and 86-93 Acura's:

    The ECU's on these cars actually have a neat little window right on the computer case. No need to jump here- just turn it to on, and watch it right there through that window.

    For both steps above, the output will be in a Morse code style of long and short lights. For example, 2 long, pause, 3 short is 23.

    While we're all feeling helpful... anyone have a pinout for the 91 ECU harnesses?? :)

    THis is great. Ask and ye shall receive.

    I get most of my info from my head, that I post. Articles are great when I need something, but to date, when LOOKING for info, not just browsing, I haven't been able to find chit I'm looking for. :p
