    Default Rewiring Ignition to 1969 40 hp Evinrude Big Twin

    I have seven wires to wire up to a five post ignition without the help of a wiring code.
    The five posts on the back of the new ignition are:
    B - Battery
    M - Magneto Circuit
    M - Magneto Circuit
    S - Solenoid
    A - Ignition Circuit

    The seven wires coming from my 1969 Evinrude 40 HP outboard 40952R are:
    (1)Brown - already connected to hot light on dash and not ignition.
    (1) Purple - already connected to push choke button on dash and not ignition, however new purple wire coming from the choke needs to be wired to one of the posts.
    (2) Black - I assume would go one each to the 2 magneto circuit posts?
    (2) White - the end of one white wire was crimped off and not connected? I assume the one white wire would go to the solenoid post?
    (1) Red - I assume needs to go to the ignition battery post.

    Does anyone have a wiring color code or can give me an educated guess on how I should connect the purple black and white wires to the back of the ignition posts? Thanks.

    "A" is for accessories.

    Red wire to B
    White wire to S
    Brown wire is not used unless you have a generator.
    TAN sensor wire to hot light
    two black wires to two M
    Ok, there are 3 purple wires on the A terminal. The go to the hot light, the choke switch, and oooops, never mind, only two purple. The 3rd would be for for electric shift--if you had one.
    Other choke switch wire is red & purple stripe.

    All wires connected to the ignition switch should have ring terminals for the screws.
